* [XFS] Remove a bunch of unused functions from XFS.Eric Sandeen2007-02-109-294/+0

* [XFS] Remove unused arguments from the XFS_BTREE_*_ADDR macros.Eric Sandeen2007-02-107-82/+39
| | | | | | | | | | | | | | | | | | | It makes it incrementally clearer to read the code when the top of a macro spaghetti-pile only receives the 3 arguments it uses, rather than 2 extra ones which are not used. Also when you start pulling this thread out of the sweater (i.e. remove unused args from XFS_BTREE_*_ADDR), a couple other third arms etc fall off too. If they're not used in the macro, then they sometimes don't need to be passed to the function calling the macro either, etc.... Patch provided by Eric Sandeen (sandeen@sandeen.net).

* [XFS] Remove unused header files for MAC and CAP checking functionality.Eric Sandeen2007-02-1019-205/+0
| | | | | | | | | | | | | | | | | | xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used anywhere in XFS at all. They are left-overs from "to be implement at some point in the future" functionality that Irix XFS has. If this functionality ever goes into Linux, it will be provided at a different layer, most likely through the security hooks in the kernel so we will never need this functionality in XFS.

* [XFS] Fix callers of xfs_iozero() to zero the correct range.Lachlan McIlroy2007-02-103-20/+20
| | | | | | | | | | | | | | The problem is the two callers of xfs_iozero() are rounding out the range to be zeroed to the end of a fsb and in some cases this extends past the new eof. The call to commit_write() in xfs_iozero() will cause the Linux inode's file size to be set too high.

* [XFS] Ensure a frozen filesystem has a clean log before writing the dummyDavid Chinner2007-02-103-7/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | record. The current Linux XFS freeze code is a mess. We flush the metadata buffers out while we are still allowing new transactions to start and then fail to flush the dirty buffers back out before writing the unmount and dummy records to the log. This leads to problems when the frozen filesystem is used for snapshots - we do log recovery on a readonly image and often it appears that the log image in the snapshot is not correct. Hence we end up with hangs, oops and mount failures when trying to mount a snapshot image that has been created when the filesystem has not been correctly frozen. To fix this, we need to move th metadata flush to after we wait for all current transactions to complete in teh second stage of the freeze. This means that when we write the final log records, the log should be clean and recovery should never occur on a snapshot image created from a frozen filesystem.

* [XFS] Fix sub-block zeroing for buffered writes into unwritten extents.David Chinner2007-02-101-4/+9
| | | | | | | | | | | | | | | | When writing less than a filesystem block of data into an unwritten extent via buffered I/O, __xfs_get_blocks fails to set the buffer new flag. As a result, the generic code will not zero either edge of the block resulting in garbage being written to disk either side of the real data. Set the buffer new state on bufferd writes to unwritten extents to ensure that zeroing occurs.

| | | | | | | | | | | | | | | | The block reservation mechanism has been broken since the per-cpu superblock counters were introduced. Make the block reservation code work with the per-cpu counters by syncing the counters, snapshotting the amount of available space and then doing a modifcation of the counter state according to the result.

* [XFS] Reduction global superblock lock contention near ENOSPC.David Chinner2007-02-102-93/+140
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing per-cpu superblock counter code uses the global superblock spin lock when we approach ENOSPC for global synchronisation. On larger machines than this code was originally tested on this can still get catastrophic spinlock contention due increasing rebalance frequency near ENOSPC. By introducing a sleeping lock that is used to serialise balances and modifications near ENOSPC we prevent contention from needlessly from wasting the CPU time of potentially hundreds of CPUs. To reduce the number of balances occuring, we separate the need rebalance case from the slow allocate case. Now, a counter running dry will trigger a rebalance during which counters are disabled. Any thread that sees a disabled counter enters a different path where it waits on the new mutex. When it gets the new mutex, it checks if the counter is disabled. If the counter is disabled, then we _know_ that we have to use the global counter and lock and it is safe to do so immediately. Otherwise, we drop the mutex and go back to trying the per-cpu counters which we know were re-enabled.

Finally, clean up all the different users of inline, __inline and __inline__ and put them under one STATIC_INLINE macro. For debug kernels the STATIC_INLINE macro uninlines those functions.

* [XFS] Fix a synchronous buftarg flush deadlock when freezing.David Chinner2007-02-101-57/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | At the last stage of a freeze, we flush the buftarg synchronously over and over again until it succeeds twice without skipping any buffers. The delwri list flush skips pinned buffers, but tries to flush all others. It removes the buffers from the delwri list, then tries to lock them one at a time as it traverses the list to issue the I/O. It holds them locked until we issue all of the I/O and then unlocks them once we've waited for it to complete. The problem is that during a freeze, the filesystem may still be doing stuff - like flushing delalloc data buffers - in the background and hence we can be trying to lock buffers that were on the delwri list at the same time. Hence we can get ABBA deadlocks between threads doing allocation and the buftarg flush (freeze) thread. Fix it by skipping locked (and pinned) buffers as we traverse the delwri buffer list.

| * ieee1394: raw1394: prevent unloading of low-level driverStefan Richter2007-02-081-19/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unloading the low-level driver module of a FireWire host can lead to all sorts of trouble if a raw1394 userspace client is using the host. Just disallow it by incrementing the LLD's module reference count on a RAW1394_REQ_SET_CARD write operation. Decrement it when the file is closed. This feature wouldn't be relevant if "modprobe -r video1394" or "modprobe -r dv1394" didn't automatically unload ohci1394 too. http://bugzilla.kernel.org/show_bug.cgi?id=7701 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Dan Dennedy <dan@dennedy.org>

| | | | | | | | | | | | | | | | Fix NULL pointer dereference on hot ejection of a FireWire card while dv1394 was loaded. http://bugzilla.kernel.org/show_bug.cgi?id=7121 I did not test card ejection with open /dev/dv1394 files yet. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
| * ieee1394: sbp2: lower block queue alignment requirementStefan Richter2007-02-081-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old setting is copy & waste from usb-storage and doesn't apply to sbp2. There is only 4-byte alignment required for everything, except for S/G table elements which have to be 8-byte aligned according to the SBP-2 spec. (They happen to be ____cacheline_aligned in our implementation. Whether that's good is another question.) We now simply don't tune block queue alignment at all. The default alignment would surely never become anything else than a multiple of 4, else tons of calls to blk_queue_dma_alignment would have to be added everywhere in drivers/...

| | | | | | | | | | | | | | | | hpsb_host.config_roms is a bitfield of which only one bit is currently used. hpsb_host.update_config_rom is only a Boolean. Neither one is accessed in hot code paths or with alignment requirements. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
