From 6a178100abf01282eb697ab62b6086b2886dfc00 Mon Sep 17 00:00:00 2001 From: Barry Naujok Date: Wed, 21 May 2008 16:42:05 +1000 Subject: [XFS] Add op_flags field and helpers to xfs_da_args The end of the xfs_da_args structure has 4 unsigned char fields for true/false information on directory and attr operations using the xfs_da_args structure. The following converts these 4 into a op_flags field that uses the first 4 bits for these fields and allows expansion for future operation information (eg. case-insensitive lookup request).
