Subject: [PATCH RFC v2 04/18] fs, block: move blk_mode_t and fop_flags_t into <linux/types.h>
Date: Tue, 16 Jun 2026 16:08:20 +0200	[thread overview]
Message-ID: <20260616-work-super-bdev_holder_global-v2-4-7df6b864028e@kernel.org> (raw)
In-Reply-To: <20260616-work-super-bdev_holder_global-v2-0-7df6b864028e@kernel.org>

blk_mode_t and fop_flags_t are both plain 'unsigned int __bitwise' flag
typedefs, exactly like the gfp_t, slab_flags_t and fmode_t that already
live in <linux/types.h>. Move them there so they are available
everywhere without having to drag in a subsystem header.
