* posix: Ensure ENOTEMPTY return on rmdirShehjar Tikoo2009-10-091-1/+4
| | | | | | | | | | | | | | | Since we added an extra step after rmdir, i.e. the lstat on parent dir as part of the NFS-friendly changes, the successful return from postparent lstat clobbers the -1 error return from rmdir. This prevents this particularly ENOTEMPTY error from being propagated to higher translators. Signed-off-by: Anand V.
