Subject: [PATCH 10/21] xfs: get directory offset when replacing a directory name
Date: Sun, 6 May 2018 10:24:43 -0700 [thread overview]
Message-ID: <1525627494-12873-11-git-send-email-allison.henderson@oracle.com> (raw)
In-Reply-To: <1525627494-12873-1-git-send-email-allison.henderson@oracle.com>
From: Mark Tinguely <tinguely@sgi.com>
Return the directory offset information when replacing an entry to the
directory.
This offset will be used as the parent pointer offset in xfs_rename.
[dchinner: forward ported and cleaned up]
[achender: rebased, changed __unint32_t to xfs_dir2_dataptr_t,
Changed typedefs to raw struct types]
