| | * [PATCH] Add blk_rq_map_kern()Mike Christie2005-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add blk_rq_map_kern which takes a kernel buffer and maps it into a request and bio. This can be used by the dm hw_handlers, old sg_scsi_ioctl, and one day scsi special requests so all requests comming into scsi will have bios. All requests having bios should allow scsi to use scatter lists for all IO and allow it to use block layer functions. Signed-off-by: Jens Axboe <axboe@suse.de>

The cause of this is that pivot_root() is not prepared to handle pivoting an unattached mount. In an initramfs environment, rootfs is the root of the namespace, and so it is not attached. This patch fixes this and related problems, by returning -EINVAL if either the current root or the new root is detached.

We now clean the dirty buffer flag under buffer lock in all cases and hence we know that whenever a buffer is starting to be journaled we either finish the pending write-out before attaching a buffer to a transaction or we won't write the buffer until the transaction is going to be committed. The test in jbd_unexpected_dirty_buffer() is redundant - remove it. Furthermore we have to clear the buffer dirty bit under the buffer lock to prevent races with buffer write-out (and hence prevent returning a buffer with IO happening).
