Hello, all.
This is the first take of prep-for-hotplug-support patchset. As the
name suggests, this patchset prepares libata for hotplug support.
This patchset contains 15 patches.
#01-02 update sata_sil (hotplug related constants, new interrupt handler)
#03-04 misc libata preps
#05-12 prepare ata_bus_probe()
#13-15 hotplug flags, extra fields, hotplug_wq
ACK, modulo the minor comments just sent.
Also, in general libata needs a rethink when it comes to workqueues.
Sometimes a single thread is more appropriate than the workqueue default
of one-thread-per-CPU. Using workqueues in the default state is quite
efficient, but can also given you a huge number of idle threads on a
$BIGNUM CPU box. Workqueues on a 16-CPU box can be pretty insane...
