ocfs2: Add quota calls for allocation and freeing of inodes and space
Add quota calls for allocation and freeing of inodes and space, also update estimates on number of needed credits for a transaction. Move out inode allocation from ocfs2_mknod_locked() because vfs_dq_init() must be called outside of a transaction. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
