| * | UBIFS: fix oops in lprops dump functionArtem Bityutskiy2011-05-131-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'dbg_dump_lprop()' is trying to detect journal head LEBs when printing, so it looks at the write-buffers. However, if we are in R/O mode, we de-allocate the write-buffers, so 'dbg_dump_lprop()' oopses. This patch fixes the issue. Note, this patch is not critical, it is only about the debugging code path, and it is unlikely that anyone but UBIFS developers would ever hit this issue.

| * | UBIFS: use ro_mount instead of MS_RDONLYArtem Bityutskiy2011-05-131-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have our own flags indicating R/O mode, and c->ro_mode is equivalent to MS_RDONLY. Let's be consistent and use UBIFS flags everywhere. This patch is just a minor cleanup. Additionally, add a comment that we are surprised with VFS behavior - as a reminder to look at this some day.

| * | UBIFS: use EROFS when emulating failuresArtem Bityutskiy2011-05-131-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the debugging failure emulation is enabled and UBIFS decides to emulate an I/O error, it uses EIO error code. In which case UBIFS switches into R/O mode later on. The for the user-space is that when a failure is emulated, the file-system sometimes returns EIO and sometimes EROFS. This makes it more difficult to implement user-space tests for the failure mode. Let's be consistent and return EROFS in all the cases. This patch is an improvement for the debugging code and does not affect the functionality at all. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is just a tiny clean-up patch. The variable name for empty address space operations is "empty_aops". Let's use consistent names for empty inode and file operations: "empty_iops" and "empty_fops", instead of inconsistent "none_inode_operations" and "none_file_operations".

| * | UBIFS: introduce lsave debuggingArtem Bityutskiy2011-05-131-0/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | Try to improve UBIFS testing coverage by randomly picking LEBs to store in lsave, rather than picking them optimally. Create a debugging version of 'populate_lsave()' for these purposes and enable it when general debugging self-checks are enabled. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBIFS: make force in-the-gaps to be a general self-checkArtem Bityutskiy2011-05-134-20/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UBIFS can force itself to use the 'in-the-gaps' commit method - the last resort method which is normally invoced very very rarely. Currently this "force int-the-gaps" debugging feature is a separate test mode. But it is a bit saner to make it to be the "general" self-test check instead. This patch is just a clean-up which should make the debugging code look a bit nicer and easier to use - we have way too many debugging options.

| * | UBIFS: improve space checking debugging featureArtem Bityutskiy2011-05-135-19/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the 'dbg_check_space_info()' function which checks whether the amount of space before re-mounting and after re-mounting is the same (remounting from R/O to R/W modes and vice-versa). The problem is that 'dbg_check_space_info()' does not save the budgeting information before re-mounting, so when an error is reported, we do not know why the amount of free space changed. This patches makes the following changes: 1. Teaches 'dbg_dump_budg()' function to accept a 'struct ubifs_budg_info' argument and print out the this argument. This way we may ask it to print any saved budgeting info, no only the current one. 2. Accordingly changes all the callers of 'dbg_dump_budg()' to comply with the changed interface. 3. Introduce a 'saved_bi' (saved budgeting info) field to 'struct ubifs_debug_info' and save the budgeting info before re-mounting there. 4. Change 'dbg_check_space_info()' and make it print both old and new budgeting information. 5. Additionally, save 'c->igx_gc_cnt' and print it if and error happens. This value contributes to the amount of free space, so we have to print it. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBIFS: rearrange the budget dumpArtem Bityutskiy2011-05-131-12/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-arrange the budget dump and make sure we first dump all the 'struct ubifs_budg_info' fields, and then the other information. Additionally, print the 'uncommitted_idx' variable. This change is required for to the following dumping function enhancement where it will be possible to dump saved 'struct ubifs_budg_info' objects, not only the current one.

| * | UBIFS: simplify dbg_dump_budg calling conventionsArtem Bityutskiy2011-05-133-12/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current 'dbg_dump_budg()' calling convention is that the 'c->space_lock' spinlock is held. However, none of the callers actually use it from contects which have 'c->space_lock' locked, so all callers have to explicitely lock and unlock the spinlock. This is not very sensible convention. This patch changes it and makes 'dbg_dump_budg()' lock the spinlock instead of imposing this to the callers. This simplifies the code a little.

| * | UBIFS: introduce a separate structure for budgeting infoArtem Bityutskiy2011-05-1311-130/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch separates out all the budgeting-related information from 'struct ubifs_info' to 'struct ubifs_budg_info'. This way the code looks a bit cleaner. However, the main driver for this is that we want to save budgeting information and print it later, so a separate data structure for this is helpful. This patch is a preparation for the further debugging output improvements. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
| * | UBIFS: use __packed instead of __attribute__((packed))Artem Bityutskiy2011-05-131-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was an attempt to standartize various "__attribute__" and other macros in order to have potentially portable and more consistent code, see commit 82ddcb040570411fc2d421d96b3e69711c670328. Note, that commit refers Rober Love's blog post, but the URL is broken, the valid URL is: http://blog.rlove.org/2005/10/with-little-help-from-your-compiler.html Moreover, nowadays checkpatch.pl warns about using __attribute__((packed)): "WARNING: __packed is preferred over __attribute__((packed))" It is not a big deal for UBIFS to use __packed, so let's do it.

| * | UBIFS: make debugfs files non-seekableArtem Bityutskiy2011-05-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turn the debufs files UBIFS maintains into non-seekable. Indeed, none of them is supposed to be seek'ed. Do this by making the '.lseek()' handler to be 'no_llseek()' and by using 'nonseekable_open()' in the '.open()' operation. This does mean an API break but this debugging API is only used by a couple of test scripts which do not rely in the 'llseek()' operation. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a lot of common code in the sys_m68k.c files. The mmu and non-mmu versions can easily be merged into a single file. There is really only 2 functions that differ in the 2 cases. A single ifdef on CONFIG_MMU can take care of this. Alternatively we could break those 2 functions out and maintain sys_m68k_no.c and sys_m68k_mm.c with just this code in it (Makefile could then just build the right one).

| * | | | sh: Ignore R_SH_NONE module relocations.Paul Mundt2011-05-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some modules may end up with R_SH_NONE relocs with the right combination of compiler/kernel config (specifically dwarf unwinder), so simply trap and ignore them instead of letting them get down to the error path.

Without this patch the old code uses clocksource_register() together with a hack that assumes a never changing clock rate (see clk_enable(), clk_get_rate() and clk_disable()). The patch uses clocksource_register_hz() with 1 Hz as initial value, then lets the ->enable() callback update the value with __clocksource_updatefreq_hz() once the struct clk has been enabled and the frequency is stable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | List elements, deleted using list_del_rcu(), cannot be freed without synchronising RCU. Further, the spinlock, used to protect the RCU writer, is called in process context, so, we don't have to save flags.
