Subject: [PATCH 1/2] xfs: mark kmalloc'd xfs_buf items as __GFP_RECLAIMABLE
Date: Thu, 13 Aug 2026 15:40:52 -0500 [thread overview]
Message-ID: <20260813204929.2253988-2-sandeen@redhat.com> (raw)
In-Reply-To: <20260813204929.2253988-1-sandeen@redhat.com>
xfs_bufs have a shrinker and are therefore reclaimable; mark
them as such in the kmalloc path, so that they are accounted
for in this way.
