In bio-based DM's clone_endio(), when target_type doesn't implement .end_io (e.g. linear) r will be always be initialized 0. So if a WRITE SAME bio fails WRITE SAME will not be disabled as intended.

2014-12-17ceph: flush inline versionYan, Zheng3-4/+23
After converting inline data to normal data, client need to flush the new i_inline_version (CEPH_INLINE_NONE) to MDS. This commit makes cap messages (sent to MDS) contain inline_version and inline_data. Client always converts inline data to normal data before data write, so the inline data length part is always zero. Signed-off-by: Yan, Zheng <[email protected]>
2014-12-17ceph: convert inline data to normal data before data writeYan, Zheng3-3/+161
Before any data write, convert inline data to normal data and set i_inline_version to CEPH_INLINE_NONE. The OSD request that saves inline data to object contains 3 operations (CMPXATTR, WRITE and SETXATTR). It compares a xattr named 'inline_version' to prevent old data overwrites newer data.

2014-12-17ceph: sync read inline dataYan, Zheng2-13/+116

2014-12-17ceph: fetch inline data when getting Fcr cap refsYan, Zheng3-18/+63
we can't use getattr to fetch inline data after getting Fcr caps, because it can cause deadlock. The solution is try bringing inline data to page cache when not holding any cap, and hope the inline data page is still there after getting the Fcr caps.

2014-12-17ceph: introduce global empty snap contextYan, Zheng3-3/+35
Current snaphost code does not properly handle moving inode from one empty snap realm to another empty snap realm. After changing inode's snap realm, some dirty pages' snap context can be not equal to inode's i_head_snap. This can trigger BUG() in ceph_put_wrbuffer_cap_refs() The fix is introduce a global empty snap context for all empty snap realm. This avoids triggering the BUG() for filesystem with no snapshot.

2014-12-17ceph: introduce a new inode flag indicating if cached dentries are orderedYan, Zheng3-19/+55
After creating/deleting/renaming file, offsets of sibling dentries may change. So we can not use cached dentries to satisfy readdir. But we can still use the cached dentries to conclude -ENOENT for lookup. This patch introduces a new inode flag indicating if child dentries are ordered. The flag is set at the same time marking a directory complete. After creating/deleting/renaming file, we clear the flag on directory inode. This prevents ceph_readdir() from using cached dentries to satisfy readdir syscall. Signed-off-by: Yan, Zheng <[email protected]>

2014-12-17ceph: fix file lock interruptionYan, Zheng4-12/+67
When a lock operation is interrupted, current code sends a unlock request to MDS to undo the lock operation. This method does not work as expected because the unlock request can drop locks that have already been acquired. The fix is use the newly introduced CEPH_LOCK_FCNTL_INTR/CEPH_LOCK_FLOCK_INTR requests to interrupt blocked file lock request. These requests do not drop locks that have alread been acquired, they only interrupt blocked file lock request. Signed-off-by: Yan, Zheng <[email protected]>
2014-12-17dm thin: fix crash by initializing thin device's refcount and completion earlierMarc Dionne1-3/+2
Commit 80e96c5484be ("dm thin: do not allow thin device activation while pool is suspended") delayed the initialization of a new thin device's refcount and completion until after this new thin was added to the pool's active_thins list and the pool lock is released.

2014-12-17dm thin: fix missing out-of-data-space to write mode transition if blocks ↵Joe Thornber1-2/+20
are released Discard bios and thin device deletion have the potential to release data blocks. If the thin-pool is in out-of-data-space mode, and blocks were released, transition the thin-pool back to full write mode. The correct time to do this is just after the thin-pool metadata commit. It cannot be done before the commit because the space maps will not allow immediate reuse of the data blocks in case there's a rollback following power failure.

2014-12-17dm thin: fix inability to discard blocks when in out-of-data-space modeJoe Thornber1-1/+1
When the pool was in PM_OUT_OF_SPACE mode its process_prepared_discard function pointer was incorrectly being set to process_prepared_discard_passdown rather than process_prepared_discard. This incorrect function pointer meant the discard was being passed down, but not effecting the mapping. As such any discard that was issued, in an attempt to reclaim blocks, would not successfully free data space.

domain being gated Audio subsystem clocks are located in separate block. On Exynos 5420 if clock for this block (from main clock domain) 'mau_epll' is gated then any read or write to audss registers will block. This kind of boot hang was observed on Arndale Octa and Peach Pi/Pit after introducing runtime PM to pl330 DMA driver. After that commit the 'mau_epll' was gated, because the "amba" clock was disabled and there were no more users of mau_epll. The system hang on one of steps: 1. Disabling unused clocks from audss block. 2. During audss GPIO setup (just before probing i2s0 because samsung_pinmux_setup() tried to access memory from audss block which was gated. Add a workaround for this by enabling the 'mau_epll' clock in probe.
