Subject: [PATCH 12/12] xfs: log NVLOOKUP xattr nvreplace operations
Date: Thu, 25 May 2023 19:09:53 -0700	[thread overview]
Message-ID: <168506072353.3743652.15630681214608046007.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <168506072168.3743652.12378764451724622618.stgit@frogsfrogsfrogs>

From: Allison Henderson <allison.henderson@oracle.com>

(Formerly titled "xfs: Add new name to attri/d" and described as
follows:

This patch adds two new fields to the atti/d.  They are nname and
nnamelen.  This will be used for parent pointer updates since a
rename operation may cause the parent pointer to update both the
name and value.  So we need to carry both the new name as well as
the target name in the attri/d.)

If high level code wants to do a deferred xattr nvreplace operation with
the NVLOOKUP flag set, we need to push this through the log.  This log
item records the old name/value pair and the new name/value pair, and
completely replaces one with the other.  Parent pointers will need this
ability to handle rename moving a child file between parents.
