| | * [GFS2] Remove gfs2_inode_attr_inSteven Whitehouse2006-11-306-24/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function wasn't really doing the right thing. There was no need to update the inode size at this point and the updating of the i_blocks field has now been moved to the places where di_blocks is updated. A result of this patch and some those preceeding it is that unlocking a glock is now a much more efficient process, since there is no longer any requirement to copy data from the gfs2 inode into the vfs inode at this point.

| | * [GFS2] Inode number is constantSteven Whitehouse2006-11-301-1/+1
| | | | | | | | | | | | | | | | | | | | | Since the inode number is constant, we don't need to keep updating it everytime we refresh the other inode fields. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
| | * [GFS2] Only set inode flags when requiredSteven Whitehouse2006-11-303-11/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were setting the inode flags from GFS2's flags far too often, even when they couldn't possibly have changed. This patch reduces the amount of flag setting going on so that we do it only when the inode is read in or when the flags have changed. The create case is covered by the "when the inode is read in" case. This also fixes a bug where we didn't set S_SYNC correctly. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
| | * [GFS2] Fix page lock/glock deadlockSteven Whitehouse2006-11-302-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a race between the glock and the page lock encountered during truncate in gfs2_readpage and gfs2_prepare_write. The gfs2_readpages function doesn't need the same fix since it only uses a try lock anyway, so it will fail back to gfs2_readpage in the case of a potential deadlock. This bug was spotted by Russell Cattelan. Cc: Russell Cattelan <cattelan@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
| | * [GFS2] Remove unused GL_DUMP flagSteven Whitehouse2006-11-302-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | There is no way to set the GL_DUMP flag, and in any case the same thing can be done with systemtap if required for debugging, so this removes it. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
| | * [GFS2] Don't copy meta_header for rgrp in and outSteven Whitehouse2006-11-301-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The meta_header for an ondisk rgrp never changes, so there is no point copying it in and back out to disk. Also there is no reason to keep a copy for each rgrp in memory. The code already checks to ensure that the header is correct before it calls the routine to copy the data in, so that we don't even need to check whether its correct on disk in the functions in ondisk.c Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

| | * [GFS2] Shrink gfs2_inode (8) - i_vnSteven Whitehouse2006-11-304-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | This shrinks the size of the gfs2_inode by 8 bytes by replacing the version counter with a one bit valid/invalid flag. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
| | * [GFS2] Shrink gfs2_inode (7) - di_payload_formatSteven Whitehouse2006-11-304-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is almost never used. Its there for backward compatibility with GFS1. It doesn't need its own field since it can always be calculated from the inode mode & flags. This saves a bit more space in the gfs2_inode. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

| | | | | | | | | | | | | | | | | | | | | Remove the di_[amc]time fields and use inode->i_[amc]time fields instead. This saves 24 bytes from the gfs2_inode. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

| | * [GFS2] Shrink gfs2_inode (2) - di_major/di_minorSteven Whitehouse2006-11-304-58/+22
| | | | | | | | | | | | | | | | | | | | | | | | This removes the device numbers from this structure by using inode->i_rdev instead. It also cleans up the code in gfs2_mknod. It results in shrinking the gfs2_inode by 8 bytes. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
| | * [GFS2] Shrink gfs2_inode (1) - di_header/di_numSteven Whitehouse2006-11-302-27/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The metadata header doesn't need to be stored in the incore struct gfs2_inode since its constant, and this patch removes it. Also, there is already a field for the inode's number in the struct gfs2_inode, so we don't need one in struct gfs2_dinode_host as well. This saves 28 bytes of space in the struct gfs2_inode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Everywhere this was called, a struct gfs2_inode was available, but despite that, it was always called with a struct gfs2_dinode as an argument. By making this change it paves the way to start eliminating fields duplicated between the kernel's struct inode and the struct gfs2_dinode. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

We only know it 1480 * was tainted so we dump it as root in mode 2. 1481 */ 1482 if (mm->dumpable == 2) { /* Setuid core dump mode */ 1483 flag = O_EXCL; /* Stop rewrite attacks */ 1484 current->fsuid = 0; /* Dump root private */ 1485 } And then filp_open follows with "flag" totally ignored. (akpm: this restores the code to Alan's original version. Andi's "Support piping into commands in /proc/sys/kernel/core_pattern" (cset d025c9db) broke it).

| * | | [PATCH] fs: make nls_cp936.c handle some U00XY characters and U20AC correctlyJun Chen2006-12-071-10/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Twenty characters in cp936 are not correctly handled. They're all in the U00 plane. nls_cp936 converts all U00XY to XY but this is not correct for some characters.(e.g. U00B7 -> A1A4, U00A8 -> A1A7). This problem is fixed by generating u2c_00 based on all c2u_xx and changing uni2char() to give U00 plane a special handling. The "€"(U20AC,80 in cp936) is also be handled properly.
