From b16ed7c114b8cca45fa87b675c431f43ff90c179 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Tue, 9 Sep 2014 11:58:07 +1000 Subject: [PATCH] xfs: combine xfs_dir_canenter into xfs_dir_createname xfs_dir_canenter and xfs_dir_createname are almost identical. Fold the former into the latter, with a helpful wrapper for the former. If createname is called without an inode number, it now only checks for space, and does not actually add the entry.
