A "real" driver for this hardware has now landed in the networking tree, so remove this old staging driver so that we don't have multiple drivers for the same hardware, and so people don't waste their time trying to clean up this old code.

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:

When Lustre servers enable 'suppress_pings', all clients will stop pinging. However, some clients may not have external mechanism to notify Lustre servers for node death and therefore need to preserve the Lustre ping.

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:
