2010-01-04bbc_envctrl: Clean up properly if kthread_run() fails.David S. Miller
In bbc_envctrl_init() we have to unlink the fan and temp instances from the lists because our caller is going to free up the 'bp' object if we return an error. We can't rely upon bbc_envctrl_cleanup() to do this work for us in this case. Reported-by: Patrick Finnegan <pat@computer-refuge.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Revamp the qdio performance statistics and move them from procfs to debugfs using the seq_file interface. Since the statistics are not intended for the general user the removal of /proc/qdio_perf should not surprise anyone. The per device statistics are disabled by default, writing 1 to /<debugfs mountpoint>/qdio/<device bus ID>/statistics enables the statistics for the given device.

2009-12-31pci: avoid compiler warning in quirks.cLinus Torvalds
Introduced by commit 5b889bf23 ("PCI: Fix build if quirks are not enabled"), which made the pci_dev_reset_methods[] array static and 'const', but didn't then change the code to match, and use a const pointer when moving it to quirks.c.

In the first iteration, those distributors might want to ship the old stack also (but blacklisted) as a fallback for their users if unforeseen problems with the newer replacement drivers are encountered. The older FireWire stack contains several known problems which are not going to be fixed; instead, those issues are addressed by the new stack. An incomplete list of these issues is kept in bugzilla: http://bugzilla.kernel.org/show_bug.cgi?id=10046 We have a guide on migration from the older to the newer stack: http://ieee1394.wiki.kernel.org/index.php/Juju_Migration

So when GART IOMMU isn't detected, agp_amd64_init isn't called. Marin Mitov reported this issue: http://marc.info/?l=linux-kernel&m=126192729110083&w=2 With this patch, agp_amd64_init() is always called via module_init (the above ifndef is removed). If agp_amd64_init() is called via gart_iommu_init() earlier, agp_amd64_init() finishes without doing anything (when it is called via module_init).

2009-12-30md: allow a resync that is waiting for other resync to complete, to be aborted.NeilBrown
If two arrays share a device, then they will not both resync at the same time. One will wait for the other to complete. While waiting, the MD_RECOVERY_INTR flag is not checked so a device failure, which would make the resync pointless, does not cause the resync to abort, so the failed device cannot be removed (as it cannot be remove while a resync is happening). So add a test for MD_RECOVERY_INTR. Reported-by: Brett Russ <bruss@netezza.com> Signed-off-by: NeilBrown <neilb@suse.de>
2009-12-30md: remove unnecessary code from do_md_runNeilBrown
Since commit dfc7064500061677720fa26352963c772d3ebe6b, ->hot_remove_disks has not removed non-failed devices from an array until recovery is no longer possible. So the code in do_md_run to get around the fact that md_check_recovery (which calls ->hot_remove_disks) would remove partially-in-sync devices is no longer needed. So remove it. Signed-off-by: NeilBrown <neilb@suse.de>
2009-12-30md: make recovery started by do_md_run() visible via sync_actionDan Williams
By default md_do_sync() will perform recovery if no other actions are specified. However, action_show() relies on MD_RECOVERY_RECOVER to be set otherwise it returns 'idle'.

2009-12-30md: fix small irregularity with start_ro module parameterNeilBrown
The start_ro modules parameter can be used to force arrays to be started in 'auto-readonly' in which they are read-only until the first write. This ensures that no resync/recovery happens until something else writes to the device. This is important for resume-from-disk off an md array. However if an array is started 'readonly' (by writing 'readonly' to the 'array_state' sysfs attribute) we want it to be really 'readonly', not 'auto-readonly'. So strengthen the condition to only set auto-readonly if the array is not already read-only. Signed-off-by: NeilBrown <neilb@suse.de>
