From 4e317ce73aecb735f389ab0d42ae3197a55265e4 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 19 Jun 2015 14:27:10 -0400 Subject: [PATCH] ufs_inode_get{frag,block}(): get rid of 'phys' argument 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.
