| * JFS: make sure right-most xtree pages have header.next set to zeroDave Kleikamp2005-10-28
| | | | | | | | | | | | | | | | The xtTruncate code was only doing this for leaf pages. When a file is horribly fragmented, we may truncate a file leaving an internal page with an invalid head.next field, which may cause a stale page to be referenced.

| * JFS: make special inodes play nicely with page balancingDave Kleikamp2005-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes up a few problems with jfs's reserved inodes. 1. There is no need for the jfs code setting the I_DIRTY bits in i_state. I am ashamed that the code ever did this, and surprised it hasn't been noticed until now. 2. Make sure special inodes are on an inode hash list. If the inodes are unhashed, __mark_inode_dirty will fail to put the inode on the superblock's dirty list, and the data will not be flushed under memory pressure. 3. Force writing journal data to disk when metapage_writepage is unable to write a metadata page due to pending journal I/O. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
* | [PATCH] gfp_t: fs/*Al Viro2005-10-28
|/ | | | | | | | | | | | | | | | | | | - ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the file systems in fs/ implementing a delete_inode() callback to call truncate_inode_pages(). One implementation note: In developing this patch I put the calls to truncate_inode_pages() at the very top of those filesystems delete_inode() callbacks in order to retain the previous behavior. I'm guessing that some of those could probably be optimized.

* | [PATCH] disk quotas fail when /etc/mtab is symlinked to /proc/mountsMark Bellon2005-09-07
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If /etc/mtab is a regular file all of the mount options (of a file system) are written to /etc/mtab by the mount command. The quota tools look there for the quota strings for their operation. If, however, /etc/mtab is a symlink to /proc/mounts (a "good thing" in some environments) the tools don't write anything - they assume the kernel will take care of things. While the quota options are sent down to the kernel via the mount system call and the file system codes handle them properly unfortunately there is no code to echo the quota strings into /proc/mounts and the quota tools fail in the symlink case. The attached patchs modify the EXT[2|3] and JFS codes to add the necessary hooks. The show_options function of each file system in these patches currently deal with only those things that seemed related to quotas; especially in the EXT3 case more can be done (later?). Jan Kara also noted the difficulty in moving these changes above the FS codes responding similarly to myself to Andrew's comment about possible VFS migration. Issue summary: - FS codes have to process the entire string of options anyway. - Only FS codes that use quotas must have a show_options function (for quotas to work properly) however quotas are only used in a small number of FS. - Since most of the quota using FS support other options these FS codes should have the a show_options function to show those options - and the quota echoing becomes virtually negligible. Based on feedback I have modified my patches from the original: JFS a missing patch has been restored to the posting EXT[2|3] and JFS always use the show_options function - Each FS has at least one FS specific option displayed - QUOTA output is under a CONFIG_QUOTA ifdef - a follow-on patch will add a multitude of options for each FS EXT[2|3] and JFS "quota" is treated as "usrquota" EXT3 journalled data check for journalled quota removed EXT[2|3] mount when quota specified but not compiled in - no changes from my original patch. I tested the patch and the codes warn but - still mount. With all due respection I believe the comments otherwise were a - misread of the patch. Please reread/test and comment. XFS patch removed - the XFS team already made the necessary changes EXT3 mixing old and new quotas are handled differently (not purely exclusive) - if old and new quotas for the same type are used together the old type is silently depricated for compatability (e.g. usrquota and usrjquota) - mixing of old and new quotas is an error (e.g. usrjquota and grpquota) Signed-off-by: Mark Bellon <mbellon@mvista.com> Acked-by: Dave Kleikamp <shaggy@austin.ibm.com> Cc: Jan Kara <jack@ucw.cz> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* | JFS: Improve sync barrier processingDave Kleikamp2005-07-27
|/ | | | | | | | | | | | | | Under heavy load, hot metadata pages are often locked by non-committed transactions, making them difficult to flush to disk. This prevents the sync point from advancing past a transaction that had modified the page. There is a point during the sync barrier processing where all outstanding transactions have been committed to disk, but no new transaction have been allowed to proceed. This is the best time to write the metadata. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>
* JFS: Fix i_blocks accounting when allocation failsDave Kleikamp2005-07-26

* JFS: Don't set log_SYNCBARRIER when log->active == 0Dave Kleikamp2005-07-25
| | | | | | | | | | If a metadata page is kept active, it is possible that the sync barrier logic continues to trigger, even if all active transactions have been phyically written to the journal. This can cause a hang, since the completion of the journal I/O is what unsets the sync barrier flag to allow new transactions to be created. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

* JFS: fsync wrong behavior when I/O failure occursQu Fuping2005-07-15
| | | | | | | | | | | | | | | | This is half of a patch that Qu Fuping submitted in April. The first part was applied to fs/mpage.c in 2.6.12-rc4. jfs_fsync should return error, but it doesn't wait for the metadata page to be uptodate, e.g.: jfs_fsync->jfs_commit_inode->txCommit->diWrite->read_metapage-> __get_metapage->read_cache_page reads a page from disk. Because read is async, when read_cache_page: err = filler(data, page), filler will not return error, it just submits I/O request and returns. So, page is not uptodate. Checking only if(IS_ERROR(mp->page)) is not enough, we should add "|| !PageUptodate(mp->page)" Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Establish a simple API for process freezing defined in linux/include/sched.h: frozen(process) Check for frozen process freezing(process) Check if a process is being frozen freeze(process) Tell a process to freeze (go to refrigerator) thaw_process(process) Restart process frozen_process(process) Process is frozen now 2. Remove all references to PF_FREEZE and PF_FROZEN from all kernel sources except sched.h 3. Fix numerous locations where try_to_freeze is manually done by a driver 4. Remove the argument that is no longer necessary from two function calls. 5. Some whitespace cleanup 6. Clear potential race in refrigerator (provides an open window of PF_FREEZE cleared before setting PF_FROZEN, recalc_sigpending does not check PF_FROZEN). This patch does not address the problem of freeze_processes() violating the rule that a task may only modify its own flags by setting PF_FREEZE. This is not clean in an SMP environment. freeze(process) is therefore not SMP safe! Signed-off-by: Christoph Lameter <christoph@lameter.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This could lead to complications when cache pages contain more than one page of jfs metadata.

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!
