Subject: [PATCH v10 1/9] fs: move kernel_read_file* to its own include file
Date: Mon, 6 Jul 2020 16:23:01 -0700 [thread overview]
Message-ID: <20200706232309.12010-2-scott.branden@broadcom.com> (raw)
In-Reply-To: <20200706232309.12010-1-scott.branden@broadcom.com>
Move kernel_read_file* out of linux/fs.h to its own linux/kernel_read_file.h
include file. That header gets pulled in just about everywhere
and doesn't really need functions not related to the general fs interface.
Suggested-by: Christoph Hellwig <hch@lst.de>
