I have recompiled Linux kernel 2.6.11.5 documentation for me and our university students again. The documentation could be extended for more sources which are equipped by structured comments for recent 2.6 kernels. I have tried to proceed with that task. I have done that more times from 2.6.0 time and it gets boring to do same changes again and again. Linux kernel compiles after changes for i386 and ARM targets. I have added references to some more files into kernel-api book, I have added some section names as well. So please, check that changes do not break something and that categories are not too much skewed. I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved by kernel convention. Most of the other changes are modifications in the comments to make kernel-doc happy, accept some parameters description and do not bail out on errors. Changed <pid> to @pid in the description, moved some #ifdef before comments to correct function to comments bindings, etc. You can see result of the modified documentation build at http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz Some more sources are ready to be included into kernel-doc generated documentation. Sources has been added into kernel-api for now. Some more section names added and probably some more chaos introduced as result of quick cleanup work. Signed-off-by:

Attached is a patch against 2.6.11.7 which tidies up the tdfxfb framebuffer size detection code a little and fixes the broken support for Voodoo4/5 cards. (I haven't tested this on a Voodoo5, however, because I don't have the hardware). Signed-off-by:

Improve the PLL frequency matching in the tdfxfb driver. Instead of requiring 64260 iterations to obtain the closest supported PLL frequency, this code does it with the same degree of accuracy in at most 768 iterations. Signed-off-by:

Ingo Oeser noticed that all that intelfbdrv.h contains are prototypes for static functions - and such prototypes don't belong into header files. This patch therefore removes drivers/video/intelfb/intelfbdrv.h and moves the prototypes to intelfbdrv.c . Signed-off-by:

This patch adds to the fbdev interface a set_cmap callback that allow the driver to "batch" palette changes. This is useful for drivers like radeonfb which might require lenghtly workarounds on palette accesses, thus allowing to factor out those workarounds efficiently. Signed-off-by:

The extra race-with-truncate-then-retry logic around ext3_get_block_handle(), which was inherited from ext2, becomes unecessary for ext3, since we have already obtained the ei->truncate_sem in ext3_get_block_handle() before calling ext3_alloc_branch(). The ei->truncate_sem is already there to block concurrent truncate and block allocation on the same inode. So the inode's indirect addressing tree won't be changed after we grab that semaphore. We could, after get the semaphore, re-verify the branch is up-to-date or not. If it has been changed, then get the updated branch. If we still need block allocation, we will have a safe version of the branch to work with in the ext3_find_goal()/ext3_splice_branch(). The code becomes more readable after remove those retry logic. The patch also clean up some gotos in ext3_get_block_handle() to make it more readable. Signed-off-by:

Since we only access reiserfs_key ->u.k_offset_v2 guts in four helper functions, we are free to sanitize those, as long as - layout of the structure is unchanged (it's on-disk object) - behaviour of these helpers is same as before. Patch kills the mess with endianness-dependent bitfields and replaces them with a single __le64. Helpers are switched to straightforward shift/and/or. Benefits: - exact same definitions for little- and big-endian architectures; no ifdefs in sight. - generate the same code on little-endian and improved on big-endian. - doesn't rely on lousy bitfields handling in gcc codegenerator. - happens to be standard C (unsigned long long is not a valid type for a bitfield; it's a gccism and not well-implemented one, at that).

comp_short_keys() massaged into sane form, which kills the last place where pointer to in_core_key (or any object containing such) would be cast to or from something else. At that point we are free to change layout of in_core_key - nothing depends on it anymore. So we drop the mess with union in there and simply use (unconditional) __u64 k_offset and __u8 k_type instead; places using in_core_key switched to those. That gives _far_ better code than current mess - on all platforms. Signed-off-by:

struct reiserfs_key cloned; (currently) identical struct in_core_key added. Places that expect host-endian data in reiserfs_key switched to in_core_key. Basically, we get annotation of reiserfs_key users and keep the resulting tree obviously equivalent to original. Signed-off-by:

For tree mount maps, a call to chdir or chroot, to a directory above the moint point directories at a certain time during the expire results in the expire incorrectly thinking the tree is not busy. This patch adds a check to see if the filesystem above the tree mount points is busy and also locks the filesystem during the tree mount expire to prevent the race. Signed-off-by:

This patch optimizes io_submit_one to call aio_run_iocb() directly if ctx->run_list is empty. When the list is empty, the operation of adding to the list, then call to __aio_run_iocbs() is unnecessary because these operations are done in one atomic step. ctx->run_list always has only one element in this case. This optimization speeds up industry standard db transaction processing benchmark by 0.2%. Signed-off-by:

Since the tail pointer in aio_ring structure never wrap ring size more than once, so a simple compare is sufficient to wrap the index around. This avoid a more expensive mod operation. Signed-off-by:

This patch removes superfluous kiocb member initialization in the AIO allocation and deallocation path. For example, in really_put_req(), right before kiocb is returned to slab, 5 variables are reset to NULL. The same variables will be initialized at the kiocb allocation time, so why bother reset them knowing that they will be set to valid data at alloc time? Another example: ki_retry is initialized in __aio_get_req, but is initialized again in io_submit_one. Signed-off-by:

I've noticed that, starting from linux-2.6.12-rc1, in the top Makefile the "cmd_tags" variable has been changed in a way incompatible with *emacs ctags. Since the "--extra" option exists only in "exuberant ctags", it should be included in the CTAGSF shell variable. Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by:

Jesper Juhl authored
This patch adds a new function valid_signal() that tests if its argument is a valid signal number. The reasons for adding this new function are: - some code currently testing _NSIG directly has off-by-one errors. Using this function instead avoids such errors. - some code currently tests unsigned signal numbers for <0 which is pointless and generates warnings when building with gcc -W. Using this function instead avoids such warnings. I considered various places to add this function but eventually settled on include/linux/signal.h as the most logical place for it. If there's some reason this is a bad choice then please let me know (hints as to a better location are then welcome of course). Signed-off-by:
