* [PATCH] revert ext3-writepages-support-for-writeback-modeAndrew Morton2005-05-05

* [PATCH] __block_write_full_page() simplificationAndrew Morton2005-05-05
| | | | | | | | | | | The `last_bh' logic probably isn't worth much. In those situations where only the front part of the page is being written out we will save some looping but in the vastly more common case of an all-page writeout if just adds more code.

* [PATCH] __block_write_full_page speedupAndrew Morton2005-05-05
| | | | | | | | | | | | Remove all those get_bh()'s and put_bh()'s by extending lock_page() to cover the troublesome regions. (get_bh() and put_bh() happen every time whereas contention on a page's lock in there happens basically never).

* [PATCH] __block_write_full_page race fixNick Piggin2005-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When running fsstress -v -d $DIR/tmp -n 1000 -p 1000 -l 2 on an ext2 filesystem with 1024 byte block size, on SMP i386 with 4096 byte page size over loopback to an image file on a tmpfs filesystem, I would very quickly hit BUG_ON(!buffer_async_write(bh)); in fs/buffer.c:end_buffer_async_write It seems that more than one request would be submitted for a given bh at a time. What would happen is the following: 2 threads doing __mpage_writepages on the same page. Thread 1 - lock the page first, and enter __block_write_full_page. Thread 1 - (eg.) mark_buffer_async_write on the first 2 buffers. Thread 1 - set page writeback, unlock page. Thread 2 - lock page, wait on page writeback Thread 1 - submit_bh on the first 2 buffers. => both requests complete, none of the page buffers are async_write, end_page_writeback is called. Thread 2 - wakes up. enters __block_write_full_page. Thread 2 - mark_buffer_async_write on (eg.) the last buffer Thread 1 - finds the last buffer has async_write set, submit_bh on that. Thread 2 - submit_bh on the last buffer. => oops. So change __block_write_full_page to explicitly keep track of the last bh we need to issue, so we don't touch anything after issuing the last request.

* [PATCH] fix race in __block_prepare_writeNick Piggin2005-05-05
| | | | | | | | | | | | | | | | | | Fix a race where __block_prepare_write can leak out an in-flight read against a bh if get_block returns an error. This can lead to the page becoming unlocked while the buffer is locked and the read still in flight. __mpage_writepage BUGs on this condition. BUG sighted on a 2-way Itanium2 system with 16K PAGE_SIZE running fsstress -v -d $DIR/tmp -n 1000 -p 1000 -l 2 where $DIR is a new ext2 filesystem with 4K blocks that is quite small (causing get_block to fail often with -ENOSPC).

| * [PATCH] JFS: Simplify creation of new iagDave Kleikamp2005-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | JFS was creating a new IAG (inode aggregate group) in one address space, and afterwards, accessing it from another. This could lead to complications when cache pages contain more than one page of jfs metadata. This patch causes the IAG to be initialized in the same address space that it is subsequently accessed with. This also elimitates an I/O, but IAG's aren't created too often.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [PATCH] ext3: remove unnecessary race then retry in ext3_get_blockMingming Cao2005-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [PATCH] reiserfs endianness: comp_short_keys() cleanupAl Viro2005-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [PATCH] reiserfs: make resize option auto-get new device sizePaolo 'Blaisorblade' Giarrusso2005-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's trivial for the resize option to auto-get the underlying device size, while it's harder for the user. I've copied the code from jfs. Since of the different reiserfs option parser (which does not use the superior match_token used by almost every other filesystem), I've had to use the "resize=auto" and not "resize" option to specify this behaviour. Changing the option parser to the kernel one wouldn't be bad but I've no time to do this cleanup in this moment. Btw, the mount(8) man page should be updated to include this option. Cc the relevant people, please (I hope I cc'ed the right people).
