At some point we added credits to people who actively helped to bring k/hr-timers along. This was lost in the big code revamp. Add it back. Signed-off-by:

Clean up the interface to hrtimers by changing the init code to pass the mode as well as the clock. This allow the init code to select the correct base and eliminates extra timer re-init code in posix-timers. We also simplify the restart interface nanosleep use. Signed-off-by:

From: Steven Rostedtrostedt@goodmis.org <rostedt@goodmis.org> CPU0 expires a posix-timer and runs the callback function. The signal is queued. After releasing the posix-timer lock and before returning to hrtimer_run_queue CPU0 gets interrupted. CPU1 delivers the queued signal and rearms the timer. CPU0 comes back to hrtimer_run_queue and sets the timer state to expired. The next modification of the timer can result in an oops, because the state information is wrong. Keep track of state = RUNNING and check if the state has been in the return path of hrtimer_run_queue. In case the state has been changed, ignore a restart request and do not touch the state variable. Signed-off-by:

This resolves bugzilla bug#5617. The oldvalue of the timer was read after the timer was cancelled, so the remaining time was always zero. Signed-off-by:

At the 2.6.12 timeframe ipmi_si_intf.c was patched to provide default register spacings in try_init_acpi() if the register spacing was set to zero, similar to code in other routines. Unfortunately, another patch was simultaneously added that exits early from try_init_acpi() if the register spacings are set to zero, circumventing the new defaults. This patch removes the early exit code and some incorrect comments that aren't present in other common code snippets. Signed-off-by:

Reduce substantially the amount of code using PF_MEMALLOC, as envisaged in the original FIXME. If you're using lvm2, for this patch to work correctly you should update to lvm2 version 2.02.01 or later and device-mapper version 1.02.02 or later. Signed-off-by:

Clean up the code responsible for the on-disk mirror logs by using the set_le_bit test_le_bit functions of ext2. That makes the BE machines keep the bitmap internally in LE order - it does mean you can't use any other type of operations on the bitmap words but that looks to be OK in this instance. The efficiency tradeoff is very minimal as you would expect for something that ext2 uses. This allows us to remove bits_to_core(), bits_to_disk() and log->disk_bits. Also increment the mirror log disk version transparently to avoid sharing with older kernels that suffered from the 64-bit BE bug. Signed-off-by:

Kernel 2.6.16-rc1 broke the ide-scsi driver: ide-scsi loads but fails to find any devices to bind to. It also triggers a message "Driver 'ide-scsi' needs updating - please use bus_type methods" from the driver core. The IDE core in 2.6.16-rc1 changed the location of an IDE driver's ->probe()/->remove()/->shutdown() methods: they are now in the ide_driver_t struct not in the gen_driver sub-struct. drivers/ide/ was updated for this change but ide-scsi.c wasn't. Hence the breakage. This patch repairs ide-scsi and also eliminates the driver core warning. Signed-off-by:

In 2.6.16-rc1 there is a small typo introduced by the 'Remove device_node addrs/n_addr' changes which prevents my Powerbook G4 sound from working: Advanced Linux Sound Architecture Driver Version 1.0.11rc2 (Wed Jan 04 08:57:20 2006 UTC). snd: can't request rsrc 0 (Sound Control: 0x80000000:80004fff) ALSA device list: No soundcards found. The patch below fixes it. Of course, the patch fixing the i2c issues ('i2c_smbus_write_i2c_block_data' patch) needs to be applied to in order for the sound to completly work.

While asynchronous reads mean a performance improvement in most cases, if the filesystem assumed that reads are synchronous, then async reads may degrade performance (filesystem may receive reads out of order, which can confuse it's own readahead logic). With sshfs a 1.5 to 4 times slowdown can be measured. There's also a need for userspace filesystems to know whether asynchronous reads are supported by the kernel or not. To achive these, negotiate in the INIT request whether async reads will be used and the maximum readahead value. Update interface version to 7.6 If userspace uses a version earlier than 7.6, then disable async reads, and set maximum readahead value to the maximum read size, as done in previous versions.

An old patch designed to fix http://bugme.osdl.org/show_bug.cgi?id=4497, "getdents gives empty/random result upon signal". If smbfs's readdir() is interupted by a signal, smb_readdir() failed to noticed that and proceeded to treat the unread-into page as valid directory contents. Fix that up by handling the -ERESTARTSYS.
