2014-08-22block: Fix BUG_ON when pi errors occurSagi Grimberg1-1/+1
When getting a pi error we get to bio_integrity_end_io with bi_remaining already decremented to 0 where we will eventually need to call bio_endio with restored original bio completion handler. Calling bio_endio invokes a BUG_ON(). We should call bio_endio_nodec instead, like what is done in bio_integrity_verify_fn.

2014-07-01bio-integrity: add "bip_max_vcnt" into struct bio_integrity_payloadGu Zheng1-9/+3
Commit 08778795 ("block: Fix nr_vecs for inline integrity vectors") from Martin introduces the function bip_integrity_vecs(get the useful vectors) to fix the issue about nr_vecs for inline integrity vectors that reported by David Milburn. But it seems that bip_integrity_vecs() will return the wrong number if the bio is not based on any bio_set for some reason(bio->bi_pool == NULL), because in that case, the bip_inline_vecs[0] is malloced directly. So here we add the bip_max_vcnt to record the count of vector slots, and cleanup the function bip_integrity_vecs(). Signed-off-by: Gu Zheng <guz.fnst@cn.fujitsu.com> Cc: Martin K.

2014-05-19block: move bio.c and bio-integrity.c from fs/ to block/Jens Axboe1-0/+657
They really belong in block/, especially now since it's not in drivers/block/ anymore. Additionally, the get_maintainer script gets it wrong when in fs/. Suggested-by: Christoph Hellwig <hch@infradead.org> Acked-by: Al Viro <viro@ZenIV.linux.org.uk> Signed-off-by: Jens Axboe <axboe@fb.com>
