From 79a628d14ec7ee9adfdc3ce04343d5ff7ec20c18 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 10 Apr 2016 18:50:48 -0400 Subject: reiserfs: switch to generic_{get,set,remove}xattr() reiserfs_xattr_[sg]et() will fail with -EOPNOTSUPP for V1 inodes anyway, and all reiserfs instances of ->[sg]et() call it and so does ->set_acl(). Checks for name length in the instances had been bogus; they should've been "bugger off if it's _exactly_ the prefix" (as generic would do on its own) and not "bugger off if it's shorter than the prefix" - that can't happen. xattr_full_name() is needed to adjust for the fact that generic instances will skip the prefix in the name passed to ->[gs]et(); reiserfs homegrown analogues didn't.
