bcache: use kmalloc to allocate bio in bch_data_verify()

2017-06-18T18:40:59+00:00

This function allocates a bio, then a collection
of pages.  It copes with failure.

It currently uses a mempool() to allocate the bio,
but alloc_page() to allocate the pages.  These fail
in different ways, so the usage is inconsistent.

Change the bio_clone() to bio_clone_kmalloc()
so that no pool is used either for the bio or the pages.

block,fs: use REQ_* flags directly

2016-11-01T15:43:26+00:00

Remove the WRITE_* and READ_SYNC wrappers, and just use the flags
directly.  Where applicable this also drops usage of the
bio_set_op_attrs wrapper.

block: export bio_free_pages to other modules

2016-09-22T13:48:03+00:00

bio_free_pages is introduced in commit 1dfa0f68c040
("block: add a helper to free bio bounce buffer pages"),
we can reuse the func in other modules after it was
imported.

bcache: use bio op accessors

2016-06-07T19:41:38+00:00

Separate the op from the rq_flag_bits and have bcache
set/get the bio using bio_set_op_attrs/bio_op.

block/fs/drivers: remove rw argument from submit_bio

2016-06-07T19:41:38+00:00

This has callers of submit_bio/submit_bio_wait set the bio->bi_rw
instead of passing it in. This makes that use the same as
generic_make_request and how we set the other bio fields.
