Staging: dst: remove from the tree

2009-12-23T19:27:45Z

DST is dead, no one is using it and upstream has abandoned it, so remove it from the tree because it is not going anywhere. Acked-by: Evgeniy Polyakov Signed-off-by: Greg Kroah-Hartman

fix the crap in dst/dcore

* don't reinvent the wheels, please - open_bdev_exclusive() is there for purpose * both open_by_devnum() and open_bdev_exclusive() return ERR_PTR(...) upon error, not NULL Signed-off-by: Al Viro

`|' has a higher precedence than `?' so since MSG_WAITALL is defined 0x100, MSG_MORE was always written to the msg_flag. Signed-off-by: Roel Kluin Acked-by: Evgeniy Polyakov Signed-off-by: Greg Kroah-Hartman

block: use normal I/O path for discard requests

2009-10-01T19:19:30Z

prepare_discard_fn() was being called in a place where memory allocation was effectively impossible. This makes it inappropriate for all but the most trivial translations of Linux's DISCARD operation to the block command set. Additionally adding a payload there makes the ownership of the bio backing unclear as it's now allocated by the device driver and not the submitter as usual. It is replaced with QUEUE_FLAG_DISCARD which is used to indicate whether the queue supports discard operations or not. blkdev_issue_discard now allocates a one-page, sector-length payload which is the right thing for the common ATA and SCSI implementations. The mtd implementation of prepare_discard_fn() is replaced with simply checking for the request being a discard. Largely based on a previous patch from Matthew Wilcox which did the prepare_discard_fn but not the different payload allocation yet. Signed-off-by: Christoph Hellwig Signed-off-by: Jens Axboe

Staging: dst: correct error-handling code

2009-09-15T19:02:06Z

dst_state_alloc returns an ERR_PTR value in an error case instead of NULL. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @match exists@ expression x, E; statement S1, S2; @@ x = dst_state_alloc(...) ... when != x = E ( * if (x == NULL || ...) S1 else S2 | * if (x == NULL && ...) S1 else S2 ) // Signed-off-by: Julia Lawall Signed-off-by: Greg Kroah-Hartman
