2005-11-02[XFS] Introduce two new mount options (nolargeio/largeio) to allowDavid Chinner6-35/+43
filesystems to expose the filesystem stripe width in stat(2) rather than the page cache size. This allows applications requiring high bandwidth to easily determine the optimum I/O size for the underlying filesystem. The default is to report the page cache size (i.e. "nolargeio").

2005-11-02[XFS] write barrier support Issue all log sync operations as orderedChristoph Hellwig12-59/+190
writes. In addition flush the disk cache on fsync if the sync cached operation didn't sync the log to disk (this requires some additional bookeping in the transaction and log code). If the device doesn't claim to support barriers, the filesystem has an extern log volume or the trial superblock write with barriers enabled failed we disable barriers and print a warning. We should probably fail the mount completely, but that could lead to nasty boot failures for the root filesystem. Not enabled by default yet, needs more destructive testing first.

2005-10-31[PATCH] Creative Audigy 2 cardbus: Add IO window wakeup magicJames Courtier-Dutton2-0/+40
This adds the magic IO wakeup code for the CardBus version of the Creative Labs Audigy 2 to the snd-emu10k1 driver. Without the magic IO enable sequence, reading from the IO region of the card will fail spectacularly, and the machine will hang. My next task will be getting the driver to actually play sound without distortion. Signed-off-by: James Courtier-Dutton <James@superbug.co.uk> [ This is a work-in-progress, but since it avoids a total lockup if the emu10k module is loaded on a machine with the cardbus card inserted, we're better off with it than without it, even if sound quality is bad right now ] Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-31[PATCH] fix __writeback_single_inode WARN_ONAndrea Arcangeli1-1/+1
When the inode count is zero in inode writeback, the WARN_ON(!(inode->i_state & I_WILL_FREE)); is broken, and needs to test for either I_WILL_FREE|I_FREEING. When the inode is in I_FREEING state, it's already out of the visibility of the vm so it can't be freed so it doesn't require the __iget and the generic_delete_inode path can call the sync internally to the lowlevel fs callback during the last iput. So the inode being in I_FREEING is also a valid condition for calling the sync with i_count == 0. The specific stack trace is this: 0xc00000007b8fb6e0 0xc00000000010118c .__writeback_single_inode +0x5c 0xc00000007b8fb6e0 0xc0000000001014dc (lr) .sync_inode +0x3c 0xc00000007b8fb790 0xc0000000001014dc .sync_inode +0x3c 0xc00000007b8fb820 0xc0000000001a5020 .ext2_sync_inode +0x64 0xc00000007b8fb8f0 0xc0000000001a65b4 .ext2_truncate +0x3f8 0xc00000007b8fba40 0xc0000000001a6940 .ext2_delete_inode +0xdc 0xc00000007b8fbac0 0xc0000000000f7a5c .generic_delete_inode +0x124 0xc00000007b8fbb50 0xc0000000000f5fe0 .iput +0xb8 0xc00000007b8fbbe0 0xc0000000000e9fd4 .sys_unlink +0x2a8 0xc00000007b8fbd10 0xc00000000001048c .ret_from_syscall_1 +0x0 Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Jeff Garzik <jgarzik@pobox.com> points out that this was wrong: we need to disable local interrupts while holding KM_IRQ0 due to IRQ sharing. And holding interrupts off during a big PIO opration is expensive, so we only want to do that if we know the page was highmem.

2005-10-31[PATCH] noop-iosched: avoid corrupted request mergingJens Axboe1-0/+1
Tejun Heo notes: "I'm currently debugging this. The problem is that we are using the generic dispatch queue directly in the noop sched and merging is NOT allowed on dispatch queues but generic handling of last_merge tries to merge requests. I'm still trying to verify this, so I'll be back with results soon." In the meantime, disable merging for noop by setting REQ_NOMERGE in elevator_noop_add_request(). Eventually, we should add a noop_list and do the dispatching like in the other io schedulers. Merging is still beneficial for noop (and it has always done it).

2005-10-30[libata] locking rewrite (== fix)Jeff Garzik2-3/+8
A lot of power packed into a little patch. This change eliminates the sharing between our controller-wide spinlock and the SCSI core's Scsi_Host lock. As the locking in libata was already highly compartmentalized, always referencing our own lock, and never scsi_host::host_lock. As a side effect, this change eliminates a deadlock from calling scsi_finish_command() while inside our spinlock.

2005-10-30[PATCH] fix missing includesTim Schmielau180-18/+299
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.
