2007-10-22ocfs2: new export opsChristoph Hellwig
OCFS2 has it's own 64bit-firendly filehandle format so we can't use the generic helpers here. I'll add a struct for the types later.

2007-10-12ocfs2: Provide convenience function for ino lookupMark Fasheh
A couple paths which needed to just match a parent dir + name pair to an inode number were a bit messy because they had to deal with ocfs2_find_files_on_disk() which returns a larger number of values. Provide a convenience function, ocfs2_lookup_ino_from_name() which internalizes all the extra accounting.

2007-05-02ocfs2: fix sparse warnings in fs/ocfs2Mark Fasheh
None of these are actually harmful, but the noise makes looking for real problems difficult. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2007-01-21ocfs2: cleanup ocfs2_iget() errorsMark Fasheh
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>
2006-12-01ocfs2: remove unused handle argument from ocfs2_meta_lock_full()Mark Fasheh
Now that this is unused and all callers pass NULL, we can safely remove it. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Remove i_generation from inode lock namesMark Fasheh
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>
