From ad3829cf1db5cf6a5dfafd54f9291b44f5fb1da8 Mon Sep 17 00:00:00 2001 From: Steve French Date: Sun, 17 Aug 2014 06:43:58 -0500 Subject: [PATCH] Incorrect error returned on setting file compressed on SMB2 When the server (for an SMB2 or SMB3 mount) doesn't support an ioctl (such as setting the compressed flag on a file) we were incorrectly returning EIO instead of EOPNOTSUPP, this is confusing e.g. doing chattr +c to a file on a non-btrfs Samba partition, now the error returned is more intuitive to the user. Also fixes error mapping on setting hardlink to servers which don't support that.
