I have been having a lot of unexplainable crashes in osc_lru_shrink lately that I could not see a good explanation for and then I found this patch that slip under the radar somehow that incorrectly converted while loop for lru list iteration into list_for_each_entry_safe totally ignoring that in the body of the loop we drop spinlocks guarding this list and move list entries around. Not sure why it was not showing up right away, perhaps some of the more recent LRU changes committed caused some extra pressure on this code that finally highlighted the breakage.

If osc_io_readahead() finds a lock that belongs to the previous instance of osc_object, the lock data pointer will be null. It has to instantiate with new instance otherwise those pages won't be destroyed at lock cancel, and then finally hit the assertion in osc_req_attr_set(). This patch revised dlmlock_at_pgoff() to call osc_match_base() to find caching locks for readahead. And new osc_object will be set to the lock if it doesn't have one yet. Signed-off-by:

In fault IO initialization, inode's mtime is saved, and after getting locks, when the IO is about to start, vvp_io_fault_start() checks the mtime's intactness. It's a false alarm, since the timestamp from MDS could be stale, we maintain mtime mainly on OST objects, and if the check in vvp_io_fault_start() happens before mtime on OST objects are merged, it will get wrong timestamp from the inode, even the timestamp it fetched in vvp_io_fault_init() could be wrong in the first place. This patch remove the mtime check in vvp_io_fault_start(). Signed-off-by:

O_WRONLY/O_RDWR open on a file will get EROFS on a read only client, but the rpc gets sent to the mdt anyway. mdt will increase the mot_write_count of the mdt object, blocking subsequent FMODE_EXEC open to the same file.

During intent open, it was found that if the parent has been migrated to another MDT, it should retry the open request with the new object, so it needs to keep the old object in the orphan list, which will be cleanup during next recovery. Note: if the client still using the old FID after next recovery, it will return -ENOENT for the application. Also enqueue the lease lock of the migrating file, then compare the lease before migration to make sure no other clients open the file at the same time. Signed-off-by:
