* tipc: Eliminate configuration for maximum number of cluster nodesAllan Stephens2011-03-131-1/+0
| | | | | | | | | | | | | | | Gets rid of the need for users to specify the maximum number of cluster nodes supported by TIPC. TIPC now automatically provides support for all 4K nodes allowed by its addressing scheme. Note: This change sets TIPC's memory usage to the amount used by a maximum size node table with 4K entries. An upcoming patch that converts the node table from a linear array to a hash table will compact the node table to a more efficient design, but for clarity it is nice to have all the Kconfig infrastruture go away separately.

* tipc: Finish streamlining of debugging codeAllan Stephens2011-01-011-38/+9
| | | | | | | | | | | | | Completes the simplification of TIPC's debugging capabilities. By default TIPC includes no debugging code, and any debugging code added by developers that calls the dbg() and dbg_macros() is compiled out. If debugging support is enabled, TIPC prints out some additional data about its internal state when certain abnormal conditions occur, and any developer-added calls to the TIPC debug macros are compiled in.

* tipc: Remove prototype code for supporting slave nodesAllan Stephens2011-01-011-1/+0
| | | | | | | | | | | | | | | | | Simplifies routines and data structures that were intended to allow TIPC to support slave nodes (i.e. nodes that did not have links to all of the other nodes in its cluster, forcing TIPC to route messages that it could not deliver directly through a non-slave node). Currently, TIPC supports only networks containing non-slave nodes, so this code is unnecessary. Note: The latest edition of the TIPC 2.0 Specification has eliminated the concept of slave nodes entirely.

* tipc: Remove obsolete native API files and exportsAllan Stephens2010-12-021-4/+10
| | | | | | | | | | | | | | | | | As part of the removal of TIPC's native API support it is no longer necessary for TIPC to export symbols for routines that can be called by kernel-based applications, nor for it to have header files that kernel-based applications can include to access the declarations for those routines. This commit eliminates the exporting of symbols by TIPC and migrates the contents of each obsolete native API include file into its corresponding non-native API equivalent. The code which was migrated in this commit was migrated intact, in that there are no technical changes combined with the relocation.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* tipc: Fix initialization sequence problems when entering network modeAllan Stephens2008-05-211-1/+1
| | | | | | | | | | | | | | This patch ensures that TIPC's topology service and configuration service are shut down before switching into "network mode". This ensures that TIPC does not mistakenly try to send unnecessary "publication withdraw" messages to other nodes before it is fully initialized for sending off-node messages. Note that the node's current network address is now updated only after the two services are shut down; this ensures that any existing connections to the topology server are terminated correctly using the old address.

|/ | | | | | | | | | | | | | This patch revamps TIPC's print buffer subsystem to eliminate support for arbitrary chains of print buffers, which were rarely needed and difficult to use safely.
