| |
-stable review patch. If anyone has any objections, please let us know.
------------------
From: Mandy Kirkconnell <alkirkco@sgi.com>
Fix nused counter. It's currently getting set to -1 rather than getting decremented by 1. Since nused never reaches 0, the "if (!free->hdr.nused)" check in xfs_dir2_leafn_remove() fails every time and xfs_dir2_shrink_inode() doesn't get called when it should. This causes extra blocks to be left on an empty directory and the directory in unable to be converted back to inline extent mode.
