Functions
struct inode *	gfs2_ilookup (struct super_block *sb, u64 no_addr, int non_block)
struct inode *	gfs2_inode_lookup (struct super_block *sb, unsigned int type, u64 no_addr, u64 no_formal_ino, int non_block)
struct inode *	gfs2_lookup_by_inum (struct gfs2_sbd *sdp, u64 no_addr, u64 *no_formal_ino, unsigned int blktype)
struct inode *	gfs2_lookup_simple (struct inode *dip, const char *name)
: The name of the inode to look for
gfs2_lookupi - Look up a filename in a directory and return its inode : An initialized holder for the directory glock : If 1, ignore the caller's permissions : An uninitialized holder for the new inode glock This can be called via the VFS filldir function when NFS is doing a readdirplus and the inode which its intending to stat isn't already in cache. In this case we must not take the directory glock again, since the readdir call will have already taken that lock. Returns: errno
struct inode *	gfs2_lookupi (struct inode *dir, const struct qstr *name, int is_root)
: Name of new dinode
create_ok - OK to create a new on-disk inode here? : Directory in which dinode is to be created : Returns: errno

: The name of the entry in the parent directory
gfs2_unlink_inode - Removes an inode from its parent dir and unlinks it : The parent directory : The inode buffer for the inode to be removed : The inode to be removed Called with all the locks and in a transaction. This will only be called for a directory after it has been checked to ensure it is empty. Returns: 0 on success, or an error

gfs2_inode_lookup - Lookup an inode : The super block : The inode number : The type of the inode non_block: Can we block on inodes that are being freed?

Returns: A VFS inode, or an error

int gfs2_permission	(	struct inode *	inode,
		int	mask
	)

gfs2_permission - : The inode : The mask to be tested : Indicates whether this is an RCU path walk or not

This may be called from the VFS directly, or from within GFS2 with the inode locked, so we look to see if the glock is already locked and only lock the glock if its not already been done.

Returns: errno
