Subject: [PATCH 02/29] xfs: add parent pointer support to attribute code
Date: Wed, 13 Mar 2024 10:53:05 -0700 [thread overview]
Message-ID: <171035223392.2613863.15143059690877826757.stgit@frogsfrogsfrogs> (raw)
In-Reply-To: <171035223299.2613863.12196197862413309469.stgit@frogsfrogsfrogs>
From: Allison Henderson <allison.henderson@oracle.com>
Add the new parent attribute type. XFS_ATTR_PARENT is used only for parent pointer
entries; it uses reserved blocks like XFS_ATTR_ROOT.
