2009-11-13md/raid5: Allow dirty-degraded arrays to be assembled when only party is ↵NeilBrown
degraded. Normally is it not safe to allow a raid5 that is both dirty and degraded to be assembled without explicit request from that admin, as it can cause hidden data corruption. This is because 'dirty' means that the parity cannot be trusted, and 'degraded' means that the parity needs to be used. However, if the device that is missing contains only parity, then there is no issue and assembly can continue. This particularly applies when a RAID5 is being converted to a RAID6 and there is an unclean shutdown while the conversion is happening. So check for whether the degraded space only contains parity, and in that case, allow the assembly. Signed-off-by: NeilBrown <neilb@suse.de>
2009-11-13Don't unconditionally set in_sync on newly added device in raid5_reshapeNeilBrown
When a reshape finds that it can add spare devices into the array, those devices might already be 'in_sync' if they are beyond the old size of the array, or they might not if they are within the array. The first case happens when we change an N-drive RAID5 to an N+1-drive RAID5. The second happens when we convert an N-drive RAID5 to an N+1-drive RAID6. So set the flag more carefully. Also, ->recovery_offset is only meaningful when the flag is clear, so only set it in that case. This change needs the preceding two to ensure that the non-in_sync device doesn't get evicted from the array when it is stopped, in the case where v0.90 metadata is used. Signed-off-by: NeilBrown <neilb@suse.de>
2009-11-13md: allow v0.91 metadata to record devices as being active but not in-sync.NeilBrown
This is a combination that didn't really make sense before. However when a reshape is converting e.g. raid5 -> raid6, the extra device is not fully in-sync, but is certainly active and contains important data. So allow that start to be meaningful and in particular get the 'recovery_offset' value (which is needed for any non-in-sync active device) from the reshape_position.

2009-11-12ASoC: move setting ac97 platformdata earlier than ac97 read/writeBarry Song
While probing, AC97 codec drivers and soc-core generically execute the following sequence: snd_soc_new_ac97_codec -> snd_soc_new_pcms -> reset ac-link/read AC97 ID to detect ->... -> set platform_data to ac97 by soc-core commit 474828a40f6ddab6e2a3475a19c5c84aa3ec7d60 adds platform_data to snd_ac97 instance. But ac97 platform data hasn't given to snd_ac97 before actual ac97 operations. Then while ac97_read access platform_data of snd_ac97 for detecting, NULL pointer oops will fire. That means old platform_data patch doesn't work in real-life cases. This patch moves the operation of setting ac97 platform_data earlier than ac97 reading/writing operations. Then it makes platform_data of AC97 become practically useful.

2009-11-13percpu: restructure pcpu_extend_area_map() to fix bugs and improve readabilityTejun Heo
pcpu_extend_area_map() had the following two bugs. * It should return 1 if pcpu_lock was dropped and reacquired but it returned 0. This could lead to oops if free_percpu() races with area map extension. * pcpu_mem_free() was called under pcpu_lock. pcpu_mem_free() might end up calling vfree() which isn't IRQ safe. This could lead to deadlock through lock order inversion via IRQ. In addition, Linus pointed out that the temporary lock dropping and subtle three-way return value of pcpu_extend_area_map() was very ugly and suggested to split the function into two - pcpu_need_to_extend() and pcpu_extend_area_map(). This patch restructures pcpu_extend_area_map() as suggested and fixes the two bugs.

2009-11-12pps: events reporting fix upRodolfo Giometti
PPS events must be recorded according to PPS's mode settings. If a process asks for (i.e.) capture-assert events only, when the PPS client calls the pps_event() function to save the current PPS event, we should verify the event type and then discard unwanted ones. Also, without this patch userland processes waiting for a specific PPS event (assert or clear but not both) may be awakened at wrong time.

2009-11-12rtc: v3020: fix v3020_mmio_read_bit()Scott Valentine
v3020_mmio_read_bit() always returns 0 when left_shift > 7. v3020_mmio_read_bit()'s return type is (unsigned char). The code returns a value masked by (1 << left_shift) that is casted to the return type. If left_shift is larger than 7, the cast will always result in a 0 return value. The problem was discovered with left_shift = 16, and the included patch corrects the problem. The bug was introduced in the last (Apr 3 2009) commit of the file, kernel versions 2.6.30 and later.

2009-11-12pidns: fix a leak in /proc dentries and inodes with pid namespaces.Sukadev Bhattiprolu
Daniel Lezcano reported a leak in 'struct pid' and 'struct pid_namespace' that is discussed in: http://lkml.org/lkml/2009/10/2/159. To summarize the thread, when container-init is terminated, it sets the PF_EXITING flag, zaps other processes in the container and waits to reap them. As a part of reaping, the container-init should flush any /proc dentries associated with the processes. But because the container-init is itself exiting and the following PF_EXITING check, the dentries are not flushed, resulting in leak in /proc inodes and dentries. This fix reverts the commit 7766755a2f249e7e0 ("Fix /proc dcache deadlock in do_exit") which introduced the check for PF_EXITING. At the time of the commit, shrink_dcache_parent() flushed dentries from other filesystems also and could have caused a deadlock which the commit fixed. But as pointed out by Eric Biederman, after commit 0feae5c47aabdde59, shrink_dcache_parent() no longer affects other filesystems. So reverting the commit is now safe. As pointed out by Jan Kara, the leak is not as critical since the unclaimed space will be reclaimed under memory pressure or by: echo 3 > /proc/sys/vm/drop_caches But since this check is no longer required, its best to remove it.
