* [PATCH] compat: fix compat_sys_openat and friendsStephen Rothwell2006-02-02
| | | | | | | | | | | | | | Most of the 64 bit architectures will zero extend the first argument to compat_sys_{openat,newfstatat,futimesat} which will fail if the 32 bit syscall was passed AT_FDCWD (which is a small negative number). Declare the first argument to be an unsigned int which will force the correct sign extension when the internal functions are called in each case. Also, do some small white space cleanups in fs/compat.c. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Acked-by: David S.

| * [PATCH] reiserfs: reiserfs hang and performance fix for data=journal modeChris Mason2006-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In data=journal mode, reiserfs writepage needs to make sure not to trigger transactions while being run under PF_MEMALLOC. This patch makes sure to redirty the page instead of forcing a transaction start in this case. Also, calling filemap_fdata* in order to trigger io on the block device can cause lock inversions on the page lock. Instead, do simple batching from flush_commit_list.

| * [PATCH] resierfs: fix reiserfs_invalidatepage race against data=orderedChris Mason2006-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a transaction has closed but before it has finished commit, there is a window where data=ordered mode requires invalidatepage to pin pages instead of freeing them. This patch fixes a race between the invalidatepage checks and data=ordered writeback, and it also adds a check to the reiserfs write_ordered_buffers routines to write any anonymous buffers that were dirtied after its first writeback loop. That bug works like this: proc1: transaction closes and a new one starts proc1: write_ordered_buffers starts processing data=ordered list proc1: buffer A is cleaned and written proc2: buffer A is dirtied by another process proc2: File is truncated to zero, page A goes through invalidatepage proc2: reiserfs_invalidatepage sees dirty buffer A with reiserfs journal head, pins it proc1: write_ordered_buffers frees the journal head on buffer A At this point, buffer A stays dirty forever Signed-off-by: Chris Mason <mason@suse.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| * [PATCH] Direct Migration V9: Avoid writeback / page_migrate() methodChristoph Lameter2006-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate a page with buffers without requiring writeback This introduces a new address space operation migratepage() that may be used by a filesystem to implement its own version of page migration. A version is provided that migrates buffers attached to pages. Some filesystems (ext2, ext3, xfs) are modified to utilize this feature. The swapper address space operation are modified so that a regular migrate_page() will occur for anonymous pages without writeback (migrate_pages forces every anonymous page to have a swap entry).

| * [PATCH] mm: hugepage accounting fixHugh Dickins2006-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.15's hugepage faulting introduced huge_pages_needed accounting into hugetlbfs: to count how many pages are already in cache, for spot check on how far a new mapping may be allowed to extend the file. But it's muddled: each hugepage found covers HPAGE_SIZE, not PAGE_SIZE. Once pages were already in cache, it would overshoot, wrap its hugepages count backwards, and so fail a harmless repeat mapping with -ENOMEM. Fixes the problem found by Don Dupuis.

| * [PATCH] fuse: fix async read for legacy filesystemsMiklos Szeredi2006-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While asynchronous reads mean a performance improvement in most cases, if the filesystem assumed that reads are synchronous, then async reads may degrade performance (filesystem may receive reads out of order, which can confuse it's own readahead logic). With sshfs a 1.5 to 4 times slowdown can be measured. There's also a need for userspace filesystems to know whether asynchronous reads are supported by the kernel or not. To achive these, negotiate in the INIT request whether async reads will be used and the maximum readahead value. Update interface version to 7.6 If userspace uses a version earlier than 7.6, then disable async reads, and set maximum readahead value to the maximum read size, as done in previous versions.

If smbfs's readdir() is interupted by a signal, smb_readdir() failed to noticed that and proceeded to treat the unread-into page as valid directory contents. Fix that up by handling the -ERESTARTSYS.

This is most easily seen with an X application that uses sub-second select/poll timeout such as emacs. You hit a key and it takes a second or so before the app responds. The two ROUND_UP() calls upon entry are using {tv,ts}_sec where it should instead be using {tv_usec,ts_nsec}, which perfectly explains the observed incorrect behavior.
