Hello, Linus.
AHCI is getting per-port irq handling and locks for better scalability. The gain is not huge but measureable with multiple high iops devices connected to the same host; however, the value of threaded IRQ handling seems negligible for AHCI and it likely will revert to non-threaded handling soon.
Another noteworthy change is George Spelvin's "libata: Un-break ATA blacklist". During 3.17 devel cycle, the libata blacklist glob matching got generalized and rewritten; unfortunately, the patch forgot to swap arguments to match the new match function and ended up breaking blacklist matching completely. It got noticed only a couple days ago so it couldn't make for-3.17-fixes either. :(
Other than the above two, nothing too interesting - the usual cleanup churns and device-specific changes.
Thanks.
