From 337684a1746f93ae107e05d90977b070bb7e39d8 Mon Sep 17 00:00:00 2001 From: Eryu Guan Date: Tue, 2 Aug 2016 19:58:28 +0800 Subject: fs: return EPERM on immutable inode In most cases, EPERM is returned on immutable inode, and there're only a few places returning EACCES. I noticed this when running LTP on overlayfs, setxattr03 failed due to unexpected EACCES on immutable inode. So converting all EACCES to EPERM on immutable inode.
