2007-01-23[PATCH] resierfs: avoid tail packing if an inode was ever mmappedVladimir Saveliev
This patch fixes a confusion reiserfs has for a long time. On release file operation reiserfs used to try to pack file data stored in last incomplete page of some files into metadata blocks. After packing the page got cleared with clear_page_dirty. It did not take into account that the page may be mmaped into other process's address space. Recent replacement for clear_page_dirty cancel_dirty_page found the confusion with sanity check that page has to be not mapped. The patch fixes the confusion by making reiserfs avoid tail packing if an inode was ever mmapped. reiserfs_mmap and reiserfs_file_release are serialized with mutex in reiserfs specific inode. reiserfs_mmap locks the mutex and sets a bit in reiserfs specific inode flags. reiserfs_file_release checks the bit having the mutex locked. If bit is set - tail packing is avoided. This eliminates a possibility that mmapped page gets cancel_page_dirty-ed.

2006-12-07[PATCH] reiserfs: do not add save links for O_DIRECT writesVladimir V. Saveliev
We add a save link for O_DIRECT writes to protect the i_size against the crashes before we actually finish the I/O. If we hit an -ENOSPC in aops->prepare_write(), we would do a truncate() to release the blocks which might have got initialized. Now the truncate would add another save link for the same inode causing a reiserfs panic for having multiple save links for the same inode. Signed-off-by: Vladimir V.

2006-10-01[PATCH] reiserfs: use generic_file_open for open() checksJeff Mahoney
The other common disk-based file systems (I checked ext[23], xfs, jfs) check to ensure that opens of files > 2 GB fail unless O_LARGEFILE is specified. They check via generic_file_open or their own open routine. ReiserFS doesn't have an f_op->open defined, and as such, it's possible to open files > 2 GB without O_LARGEFILE. This patch adds the f_op->open member to conform with the expected behavior.

2006-07-10[PATCH] reiserfs: fix journaling issue regarding fsync()Hisashi Hifumi
When write() extends a file(i_size is increased) and fsync() is called, change of inode must be written to journaling area through fsync(). But,currently the i_trans_id is not correctly updated when i_size is increased. So fsync() does not kick the journal writer. Reiserfs_file_write() already updates the transaction when blocks are allocated, but the case when i_size increases and new blocks are not added is not correctly treated. Following patch fix this bug.

2006-03-30[PATCH] Introduce sys_splice() system callJens Axboe
This adds support for the sys_splice system call. Using a pipe as a transport, it can connect to files or sockets (latter as output only). From the splice.c comments: "splice": joining two ropes together by interweaving their strands. This is the "extended pipe" functionality, where a pipe is used as an arbitrary in-memory buffer. Think of a pipe as a small kernel buffer that you can use to transfer data from one end to the other. The traditional unix read/write is extended with a "splice()" operation that transfers data buffers to or from a pipe buffer. Named by Larry McVoy, original implementation from Linus, extended by Jens to support splicing to files and fixing the initial implementation bugs.

This is a conversion to make the various file_operations structs in fs/ const.

write occurs w/ O_SYNC When an error occurs in reiserfs_file_write before any data is written, and O_SYNC is set, the return code of generic_osync_write will overwrite the error code, losing it. This patch ensures that generic_osync_inode() doesn't run under an error condition, losing the error. This duplicates the logic from generic_file_buffered_write().

2006-01-10[PATCH] replace inode_update_time with file_update_timeChristoph Hellwig
To allow various options to work per-mount instead of per-sb we need a struct vfsmount when updating ctime and mtime. This preparation patch replaces the inode_update_time routine with a file_update_atime routine so we can easily get at the vfsmount. (and the file makes more sense in this context anyway). Also get rid of the unused second argument - we always want to update the ctime when calling this routine.

2005-09-13[PATCH] reiserfs: use mark_inode_dirty instead of reiserfs_update_sdChris Mason
reiserfs should use mark_inode_dirty during reiserfs_file_write and reiserfs_commit_write. This makes sure the inode is properly flagged as dirty, which is used during O_SYNC to decide when to trigger log commits. This patch also removes the O_SYNC check from reiserfs_commit_write, since that gets dealt with properly at higher layers once we start using mark_inode_dirty.

2005-07-12reiserfs: run scripts/Lindent on reiserfs codeLinus Torvalds
This was a pure indentation change, using: scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h to make reiserfs match the regular Linux indentation style. As Jeff Mahoney <jeffm@suse.com> writes: The ReiserFS code is a mix of a number of different coding styles, sometimes different even from line-to-line. Since the code has been relatively stable for quite some time and there are few outstanding patches to be applied, it is time to reformat the code to conform to the Linux style standard outlined in Documentation/CodingStyle. This patch contains the result of running scripts/Lindent against fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the code can be made to look better, but I'd rather keep those patches separate so that there isn't a subtle by-hand hand accident in the middle of a huge patch. To be clear: This patch is reformatting *only*. A number of patches may follow that continue to make the code more consistent with the Linux coding style. Hans wasn't particularly enthusiastic about these patches, but said he wouldn't really oppose them either. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
