The 'ubifs_scan()' function returns -EUCLEAN if something is corrupted and recovery is needed, otherwise it returns other error codes. However, in few places UBIFS does not check the error codes and runs recovery. This patch changes this behavior and makes UBIFS start recovery only on -EUCLEAN errors.

At the moment UBIFS print large and scary error messages and flash dumps in case of nearly any corruption, even if it is a recoverable corruption. For example, if the master node is corrupted, ubifs_scan() prints error dumps, then UBIFS recovers just fine and goes on. This patch makes UBIFS print scary error messages only in real cases, which are not recoverable. It adds 'quiet' argument to the 'ubifs_scan()' function, so the caller may ask 'ubi_scan()' not to print error messages if the caller is able to do recovery.

Nowadays VFS always synchronizes all dirty inodes and pages before calling '->sync_fs()', so remove unneeded 'generic_sync_sb_inodes()' from 'ubifs_sync_fs()'.

The BKL was pushed down from VFS to the file-systems. It used to serialize mount/unmount/remount and prevented more than one instance of the same file-system from doing mount/umount/remount at the same time. But it is OK for UBIFS and it does not need any additional locking for these cases. Thus, kick the BKL out of UBIFS. Signed-off-by: NArtem Bityutskiy <Artem.Bityutskiy@nokia.com>

for some reason, this structure gets compiled as 36 bytes in some files (the ones that alloacte it) but 40 bytes in others (the ones that use it). The cause is an off_t type that gets a different size in different compilation units for some yet-to-be-explained reason. But the effect is disasterous; the size/offset members of the struct are at different offsets, and result in mostly complete garbage. The parser in perf is so robust that this all gets hidden, and after skipping an certain amount of samples, it recovers.... so this bug is not normally noticed. .... except when you want every sample to be exact. Fix this by just using an explicitly sized type.

由 Peter Zijlstra 提交于
Anton noted that for inherited counters the counter-id as provided by PERF_SAMPLE_ID isn't mappable to the id found through PERF_RECORD_ID because each inherited counter gets its own id. His suggestion was to always return the parent counter id, since that is the primary counter id as exposed. However, these inherited counters have a unique identifier so that events like PERF_EVENT_PERIOD and PERF_EVENT_THROTTLE can be specific about which counter gets modified, which is important when trying to normalize the sample streams. This patch removes PERF_EVENT_PERIOD in favour of PERF_SAMPLE_PERIOD, which is more useful anyway, since changing periods became a lot more common than initially thought -- rendering PERF_EVENT_PERIOD the less useful solution (also, PERF_SAMPLE_PERIOD reports the more accurate value, since it reports the value used to trigger the overflow, whereas PERF_EVENT_PERIOD simply reports the requested period changed, which might only take effect on the next cycle). This still leaves us PERF_EVENT_THROTTLE to consider, but since that _should_ be a rare occurrence, and linking it to a primary id is the most useful bit to diagnose the problem, we introduce a PERF_SAMPLE_STREAM_ID, for those few cases where the full reconstruction is important.
