2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Maxime Bizon commit bc146d23d1358af43f03793c3ad8c9f16bbcffcb upstream. I'm using ide on 2.6.30.1 with xfs filesystem. I noticed a kernel memory leak after writing lots of data, the kmalloc-96 slab cache keeps growing. It seems the struct ide_cmd kmalloced by idedisk_prepare_flush is never kfreed. Commit a09485df9cda49fbde2766c86eb18a9cae585162 ("ide: move request type specific code from ide_end_drive_cmd() to callers (v3)") and f505d49ffd25ed062e76ffd17568d3937fcd338c ("ide: fix barriers support") cause this regression, cmd->rq must now be set for ide_complete_cmd to honor the IDE_TFLAG_DYN flag.
