From 698b8223631472bf982ed570b0812faa61955683 Mon Sep 17 00:00:00 2001 From: Dave Chiluk Date: Tue, 28 May 2013 16:06:08 -0500 Subject: [PATCH] ncpfs: fix rmdir returns Device or resource busy 1d2ef5901483004d74947bbf78d5146c24038fe7 caused a regression in ncpfs such that directories could no longer be removed. This was because ncp_rmdir checked to see if a dentry could be unhashed before allowing it to be removed. Since 1d2ef5901483004d74947bbf78d5146c24038fe7 introduced a change that incremented dentry->d_count causing it to always be greater than 1 unhash would always fail. Thus causing the error path in ncp_rmdir to always be taken. Removing this error path is safe as unhashing is still accomplished by calls to dput from vfs_rmdir.
