From eaa47d8612783807ef9703ebc9bf0d0f0455bf62 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 28 Aug 2008 06:21:16 -0400 Subject: btrfs: optmize listxattr The ->list handler is really not useful at all, because we always call btrfs_xattr_generic_list anyway. After this is done find_btrfs_xattr_handler becomes unused, and it becomes obvious that the temporary name buffer allocation isn't needed but we can directly copy into the supplied buffer. Tested with various getfattr -d calls on varying xattr lists.
