From 62f469b596dd0aadf046a69027087c18db43734e Mon Sep 17 00:00:00 2001 From: Boaz Harrosh Date: Sun, 24 May 2009 20:04:26 +0300 Subject: [SCSI] libosd: osd_req_{read,write} takes a length parameter For supporting of chained-bios we can not inspect the first bio only, as before. Caller shall pass the total length of the request, ie. sum_bytes(bio-chain). Also since the bio might be a chain we don't set it's direction on behalf of it's callers. The bio direction should be properly set prior to this call. So fix a couple of write users that now need to set the bio direction properly [In this patch I change both library code and user sites at exofs, to make it easy on integration. It should be submitted via James's scsi-misc tree.] Signed-off-by: Boaz Harrosh CC: Jeff Garzik Signed-off-by: James Bottomley --- fs/exofs/inode.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'fs/exofs') diff --git a/fs/exofs/inode.c b/fs/exofs/inode.c index ba8d9fab4693..f79e8e58c3a2 100644 --- a/fs/exofs/inode.c +++ b/fs/exofs/inode.c @@ -266,7 +266,7 @@ static int read_exec(struct page_collect *pcol, bool is_sync) goto err; } - osd_req_read(or, &obj, pcol->bio, i_start); + osd_req_read(or, &obj, i_start, pcol->bio, pcol->length); if (is_sync) { exofs_sync_op(or, pcol->sbi->s_timeout, oi->i_cred); @@ -522,7 +522,8 @@ static int write_exec(struct page_collect *pcol) *pcol_copy = *pcol; - osd_req_write(or, &obj, pcol_copy->bio, i_start); + pcol_copy->bio->bi_rw |= (1 << BIO_RW); /* FIXME: bio_set_dir() */ + osd_req_write(or, &obj, i_start, pcol_copy->bio, pcol_copy->length); ret = exofs_async_op(or, writepages_done, pcol_copy, oi->i_cred); if (unlikely(ret)) { EXOFS_ERR("write_exec: exofs_async_op() Faild\n"); -- cgit v1.2.2
