Subject: [PATCH V2 1/5] xfs: remove kmem_zone_zalloc()
Date: Wed, 20 Nov 2019 11:44:21 +0100 [thread overview]
Message-ID: <20191120104425.407213-2-cmaiolino@redhat.com> (raw)
In-Reply-To: <20191120104425.407213-1-cmaiolino@redhat.com>
Use kmem_cache_zalloc() directly.
We can use __GFP_NOFAIL to loop infinitely on a memory allocation request, which
also has an implied congestion_wait()
Reviewed-by: Darrick J. Wong <darrick.wong@oracle.com>
