From 9c02f2b02e29a2244e36c6e1f246080d8afc6cff Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 18 Sep 2008 09:31:53 -0700 Subject: block: cleanup some of the integrity stuff in blkdev.h Don't put functions that are only used in fs/bio-integrity.c in blkdev.h, it's much cleaner to just keep it in there. Also kill completely unused bdev_get_tag_size() Signed-off-by: Jens Axboe --- fs/bio-integrity.c | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) (limited to 'fs/bio-integrity.c') diff --git a/fs/bio-integrity.c b/fs/bio-integrity.c index c3e174b35fe6..ba4ada08564a 100644 --- a/fs/bio-integrity.c +++ b/fs/bio-integrity.c @@ -150,6 +150,29 @@ int bio_integrity_add_page(struct bio *bio, struct page *page, } EXPORT_SYMBOL(bio_integrity_add_page); +static struct blk_integrity *bdev_get_integrity(struct block_device *bdev) +{ + return bdev->bd_disk->integrity; +} + +static int bdev_integrity_enabled(struct block_device *bdev, int rw) +{ + struct blk_integrity *bi = bdev_get_integrity(bdev); + + if (bi == NULL) + return 0; + + if (rw == READ && bi->verify_fn != NULL && + (bi->flags & INTEGRITY_FLAG_READ)) + return 1; + + if (rw == WRITE && bi->generate_fn != NULL && + (bi->flags & INTEGRITY_FLAG_WRITE)) + return 1; + + return 0; +} + /** * bio_integrity_enabled - Check whether integrity can be passed * @bio: bio to check @@ -313,6 +336,14 @@ static void bio_integrity_generate(struct bio *bio) } } +static inline unsigned short blk_integrity_tuple_size(struct blk_integrity *bi) +{ + if (bi) + return bi->tuple_size; + + return 0; +} + /** * bio_integrity_prep - Prepare bio for integrity I/O * @bio: bio to prepare -- cgit v1.2.1
