From: Filipe Manana <fdmanana@xxxxxxxx>
The previous patches added support for operations to set and get xattrs on
regular files and directories, this patch just adds one operation to delete
xattrs on files and directories.
Signed-off-by: Filipe Manana <fdmanana@xxxxxxxx>
---
V2: Use a different name for the operation (delfattr) and make use of the
helper functions for opening and closing files or directories, introduced
in the first patch of this series.
V3: Simplified implementation to not need to open a file descriptor and
use a path string instead.
