Kent Overstreet 3816199506 block: add bio_iov_iter_get_pages() ... This is a helper that pins down a range from an iov_iter and adds it to a bio without requiring a separate memory allocation for the page array. It will be used for upcoming direct I/O implementations for block devices and iomap based file systems. Signed-off-by: Kent Overstreet <kent.overstreet@gmail.com> [hch: ported to the iov_iter interface, renamed and added comments. All blame should be directed to me and all fame should go to Kent after this!] Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@fb.com> (cherry picked from commit 9cd56d916aa481ce8f56d9c5302a6ed90c2e0b5f)		2016-11-30 13:02:03 +11:00
