Subject: [PATCH RFC 1/8] fs, block: move blk_mode_t and fop_flags_t into <linux/types.h>
Date: Tue, 02 Jun 2026 12:10:07 +0200	[thread overview]
Message-ID: <20260602-work-super-bdev_holder_global-v1-1-bb0fd82f3861@kernel.org> (raw)
In-Reply-To: <20260602-work-super-bdev_holder_global-v1-0-bb0fd82f3861@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.
