Subject: [git patches] libata fixes
More fixes coming too - the thing Alan's talking about, and an ata_piix
leak-on-err fix. By Monday-ish (its a working weekend).
Please pull from 'upstream-linus' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev.git upstream-linus
to receive the following updates:
