Just pass NULL as locked_page in case of first block in the indirect chain. Old calling conventions aside, a reason for having 'phys' was that ufs_inode_getfrag() used to be able to do _two_ allocations - indirect block and extending/reallocating a tail. We needed locked_page for the latter (it's a data), but we also needed to figure out that indirect block is metadata. So we used to pass non-NULL locked_page in all cases *and* used NULL phys as indication of being asked to allocate an indirect. With tail unpacking taken into a separate function we don't need those convolutions anymore. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
