From bd976e52725965ddcceb9abecbcc7ca46863665c Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Mon, 1 Jul 2019 14:09:16 +0900 Subject: block: Kill gfp_t argument of blkdev_report_zones() Only GFP_KERNEL and GFP_NOIO are used with blkdev_report_zones(). In preparation of using vmalloc() for large report buffer and zone array allocations used by this function, remove its "gfp_t gfp_mask" argument and rely on the caller context to use memalloc_noio_save/restore() where necessary (block layer zone revalidation and dm-zoned I/O error path).
