This is a false positive when grepping ... change it to be what the NFS

By using the TASK_KILLABLE infrastructure, we can get rid of the 'intr'
mount option. We have to use _killable everywhere instead of _interruptible
as we get rid of rpc_clnt_sigmask/sigunmask.

Michel Dänzr has bisected an interactivity problem with
plus-reniced tasks back to this commit:
810e95ccd58d91369191aa4ecc9e6d4a10d8d0c8 is first bad commit
commit 810e95ccd58d91369191aa4ecc9e6d4a10d8d0c8

sched: another wakeup_granularity fix
unit mis-match: wakeup_gran was used against a vruntime
fix this by assymetrically scaling the vtime of positive reniced
tasks.

The reason why we are getting better wakeup latencies for
!FAIR_USER_SCHED is because of this snippet of code in place_entity():
if (!initial) {
/* sleeps upto a single latency don't count. */
if (sched_feat(NEW_FAIR_SLEEPERS) && entity_is_task(se))
^^^^^^^^^^^^^^^^^^
vruntime -= sysctl_sched_latency;
/* ensure we never gain time by being placed backwards. */
vruntime = max_vruntime(se->vruntime, vruntime);
}
NEW_FAIR_SLEEPERS feature gives credit for sleeping only to tasks and
not group-level entities. With the patch attached, I could see that
wakeup latencies with FAIR_USER_SCHED are restored to the same level as
!FAIR_USER_SCHED.

This is based on pseudo-random playing around with the capabilities.
With ca0102 this card gives no output atall, ca0108 appears to work
fine, so it rather looks similar to the EMU1010b/EMU1010 changes.
Some other people seem to have succeeded in using this aswell:

Mirodock and also use headpohone output on host cardbus card as another

With the Solo1 (es1938) I got a lot of xrun's during capture on my machine.
Tracing that down it seems to be comming from reading ocassionaly bad hw
pointers from the chip. This patch uses more checking to avoid that false
pointer reads.
Failed reads are giving back the last good value read instead of spinning in
a tight loop, which seems more appropriate to me in an interrupt. I think I
saw this trick used in another driver
