* [PATCH] sem2mutex: fs/Ingo Molnar2006-03-26

* 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: 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>
* [PATCH] Cleanup patch for process freezingChristoph Lameter2005-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* JFS: Fix compiler warning in jfs_logmgr.cDave Kleikamp2005-06-03
| | | | | | | | | | | fs/jfs/jfs_logmgr.c: In function `jfs_flush_journal': fs/jfs/jfs_logmgr.c:1632: warning: unused variable `mp' Some debug code in jfs_flush_journal does nothing when CONFIG_JFS_DEBUG is not defined. Place the whole code segment within an ifdef to avoid unnecessary code to be compiled and the warning to be issued. Signed-off-by: Dave Kleikamp <shaggy@austin.ibm.com>

* [PATCH] JFS: Write journal sync points more oftenDave Kleikamp2005-05-03
| | | | | | | | | | | | | | This patch adds jfs_syncpt, which calls lmLogSync to write sync points to the journal both in jfs_sync_fs and when sync barrier processing completes. lmLogSync accomplishes two things: 1) it pushes logged-but-dirty metadata pages to disk, and 2) it writes a sync record to the journal so that jfs_fsck doesn't need to replay more transactions than is necessary.

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!
