* Btrfs: Replace the big fs_mutex with a collection of other locksChris Mason2008-09-25
| | | | | | | | Extent alloctions are still protected by a large alloc_mutex. Objectid allocations are covered by a objectid mutex Other btree operations are protected by a lock on individual btree nodes Signed-off-by: Chris Mason <chris.mason@oracle.com>

* Btrfs: Make ACLs return EOPNOTSUPP for nowJosef Bacik2008-09-25
| | | | | | | | | | | | | | There was a slight problem with ACL's returning EINVAL when you tried to set an ACL. This isn't correct, we should be returning EOPNOTSUPP, so I did a very ugly thing and just commented everybody out and made them return EOPNOTSUPP. This is only temporary, I'm going back to implement ACL's, but Chris wants to push out a release so this will suffice for now. Also Yan suggested setting reada to -1 in the delete case to enable backwards readahead, and in the listxattr case I moved path->reada = 2; to after the if (!path) check so we can avoid a possible null dereference. Thank you, Signed-off-by: Chris Mason <chris.mason@oracle.com>
