2012-05-15quota: Get rid of nested I_MUTEX_QUOTA locking subclassJan Kara
So far i_mutex was ranking above dqonoff_mutex and i_mutex on quota files was special and ranking below dqonoff_mutex (and several other locks). However there's no real need for i_mutex on quota files to be special. IO on quota files is serialized by dqio_mutex anyway so we don't need to take i_mutex when writing to quota files. Other places where we take i_mutex on quota file can accomodate standard i_mutex lock ranking, we only need to change the lock ranking to be dqonoff_mutex > i_mutex which is a matter of changing documentation because there's no place which would enforce ordering in the other direction.

2012-05-15ext2: Remove i_mutex use from ext2_quota_write()Jan Kara
We don't need i_mutex in ext2_quota_write() because writes to quota file are serialized by dqio_mutex anyway. Changes to quota files outside of quota code are forbidded and enforced by NOATIME and IMMUTABLE bits. Signed-off-by: Jan Kara <jack@suse.cz>

2012-05-15quota: Fix double lock in add_dquot_ref() with CONFIG_QUOTA_DEBUGJan Kara
When CONFIG_QUOTA_DEBUG is enabled we call inode_get_rsv_space() from add_dquot_ref() while holding i_lock. But inode_get_rsv_space() is trying to get i_lock as well resulting in double lock. Fix the problem by moving inode_get_rsv_space() call out of i_lock. Reported-and-analyzed-by: Jie Liu <jeff.liu@oracle.com> Signed-off-by: Jan Kara <jack@suse.cz>
2012-05-15jbd: Write journal superblock with WRITE_FUA after checkpointingJan Kara
If journal superblock is written only in disk's caches and other transaction starts reusing space of the transaction cleaned from the log, it can happen blocks of a new transaction reach the disk before journal superblock. When power failure happens in such case, subsequent journal replay would still try to replay the old transaction but some of it's blocks may be already overwritten by the new transaction. For this reason we must use WRITE_FUA when updating log tail and we must first write new log tail to disk and update in-memory information only after that. Signed-off-by: Jan Kara <jack@suse.cz>
2012-05-15jbd: protect all log tail updates with j_checkpoint_mutexJan Kara
There are some log tail updates that are not protected by j_checkpoint_mutex. Some of these are harmless because they happen during startup or shutdown but updates in journal_commit_transaction() and journal_flush() can really race with other log tail updates (e.g. someone doing journal_flush() with someone running cleanup_journal_tail()). So protect all log tail updates with j_checkpoint_mutex. Signed-off-by: Jan Kara <jack@suse.cz>
2012-05-15jbd: Split updating of journal superblock and marking journal emptyJan Kara
There are three case of updating journal superblock. In the first case, we want to mark journal as empty (setting s_sequence to 0), in the second case we want to update log tail, in the third case we want to update s_errno. Split these cases into separate functions. It makes the code slightly more straightforward and later patches will make the distinction even more important. Signed-off-by: Jan Kara <jack@suse.cz>

2012-05-15ath9k_hw: Fix RTT calibrationSujith Manoharan
This patch fixes multiple issues with the current RTT implementation in ath9k. * The data that is obtained from the RTT interface registers are stored in 31:5 - mask out the extra bits when reading them. * A history buffer is maintained which is not needed at all. Remove this array and just store the baseband data for each chain (or bank). * A 'num_readings' variable was being used to handle the last entry. But it was being used in an improper manner, with the result that the RTT values were never being written to the RTT Interface registers. Fix this by using a simple flag. * Stop baseband operations before programming the calibration values to the HW. * Do not restore RX gain settings as part of RTT.
