Jan Kara d769b3c2ab isofs: Remove global fs lock ... sbi->s_mutex isn't needed for isofs at all so we can just remove it. Generally, since isofs is always mounted read-only, filesystem structure cannot change under us. So buffer_head contents stays constant after it's filled in. That leaves us with possible changes of global data structures. Superblock changes only during filesystem mount (even remount does not change it), inodes are only filled in during reading from disk. So there are no changes of these structures to bother about. Arguments why sbi->s_mutex can be removed at each place: isofs_readdir: Accesses sb, inode, filp, local variables => s_mutex not needed isofs_lookup: Protected by directory's i_mutex. Accesses sb, inode, dentry, local variables => s_mutex not needed rock_ridge_symlink_readpage: Protected by page lock. Accesses sb, inode, local variables => s_mutex not needed.
