* ocfs2: fix sparse warnings in fs/ocfs2Mark Fasheh2007-05-021-2/+4
| | | | | | | None of these are actually harmful, but the noise makes looking for real problems difficult. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: cleanup ocfs2_iget() errorsMark Fasheh2007-01-211-4/+1
| | | | | | | Get rid of some error prints in the ocfs2_iget() path from ocfs2_get_dentry(). NFSD can easily cause us to read stale inodes. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: remove unused handle argument from ocfs2_meta_lock_full()Mark Fasheh2006-12-011-1/+1
| | | | | | Now that this is unused and all callers pass NULL, we can safely remove it. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Remove i_generation from inode lock namesMark Fasheh2006-09-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | OCFS2 puts inode meta data in the "lock value block" provided by the DLM. Typically, i_generation is encoded in the lock name so that a deleted inode on and a new one in the same block don't share the same lvb. Unfortunately, that scheme means that the read in ocfs2_read_locked_inode() is potentially thrown away as soon as the meta data lock is taken - we cannot encode the lock name without first knowing i_generation, which requires a disk read. This patch encodes i_generation in the inode meta data lvb, and removes the value from the inode meta data lock name. This way, the read can be covered by a lock, and at the same time we can distinguish between an up to date and a stale LVB. This will help cold-cache stat(2) performance in particular. Since this patch changes the protocol version, we take the opportunity to do a minor re-organization of two of the LVB fields. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: Hook rest of the file system into dentry locking APIMark Fasheh2006-09-241-0/+4
| | | | | | | Actually replace the vote calls with the new dentry operations. Make any necessary adjustments to get the scheme to work. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
