From 9f2179a5e72b794f8af22a6818d83d1600050c5c Mon Sep 17 00:00:00 2001 From: David Sterba Date: Fri, 2 Jun 2017 17:55:44 +0200 Subject: [PATCH] btrfs: remove redundant parameters from btrfs_bio_alloc All callers pass gfp_flags=GFP_NOFS and nr_vecs=BIO_MAX_PAGES. submit_extent_page adds __GFP_HIGH that does not make a difference in our case as it allows access to memory reserves but otherwise does not change the constraints.
