While I'm glad to finally see the hole fixed whereby passing an invalid
IRQ trigger type to request_irq() would be ignored, the current diagnostic
isn't quite useful. Fixed by also listing the trigger type which was
rejected.Signed-off-by: David Brownell

In relay's current read implementation, if the buffer is completely full
but hasn't triggered the buffer-full condition (i.e. the last write
didn't cross the subbuffer boundary) and the last subbuffer is exactly
full, the subbuffer accounting code erroneously finds nothing available.
This patch fixes the problem.Signed-off-by: Tom Zanussi

The current implementation reports the structure name as
VMCOREINFO_OSRELEASE in VMCOREINFO, e.g.VMCOREINFO_OSRELEASE=init_uts_ns.name.release
That doesn't make sense because it's always the same. Instead, use the
value, e.g.VMCOREINFO_OSRELEASE=2.6.26-rc3
That's also what the 'makedumpfile -g' does.

According to MMC-3 (or any later versions) READ TOCs are mandatory
commands and have nothing to do with CDC_PLAY_AUDIO. I have no idea why
the check was put there in the first place but it now only breaks
automatic actions on certain drives.Note that this test was only effective when ide-cdrom was being used
as sr didn't mask CDC_PLAY_AUDIO according to the capabilities.Signed-off-by: Tejun Heo

Aesthetic regards aside, commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667
still leaves a bug in the error message, because it uses the unconverted
big-endian value for printk.Fix this by using a local variable in machine byte order. The result is
correct, more readable, and also produces slightly shorter code on i386.Signed-off-by: Petr Tesarik

("ide: add ide_device_{get,put}() helpers"). ide_device_put() is called
before kref_put() in ide_cd_put() so IDE device is already gone by the time
ide_cd_release() is reached.Fix it by calling ide_device_get() before kref_get() and ide_device_put()
after kref_put() in all affected device drivers.v2:
Brown paper bag time. In v1 cd->drive was referenced after dropping last
reference on cd object (which could result in OOPS in ide_device_put() as
reported/debugged by Mariusz Kozlowski). Fix it by caching cd->drive in
the local variable (fix other device drivers too).Reported-by: Benjamin Herrenschmidt

Like the page lock change, this also requires name change, so convert the
raw test_and_set bitop to a trylock.Signed-off-by: Nick Piggin
Signed-off-by: Linus Torvalds -
Converting page lock to new locking bitops requires a change of page flag
operation naming, so we might as well convert it to something nicer
(!TestSetPageLocked_Lock => trylock_page, SetPageLocked => set_page_locked).This also facilitates lockdeping of page lock.
