[PATCH 5.11 020/120] btrfs: fix slab cache flags for free space tree bitmap

[Greg Kroah-Hartman]

From: David Sterba <dste...@suse.com>

commit 34e49994d0dcdb2d31d4d2908d04f4e9ce57e4d7 upstream.

The free space tree bitmap slab cache is created with SLAB_RED_ZONE but
that's a debugging flag and not always enabled. Also the other slabs are
created with at least SLAB_MEM_SPREAD that we want as well to average
the memory placement cost.
