-Subject: [PATCH] sdio: use interruptible sleep in kthread main loops
-
-My FreeRunner's load average was leveling off at 2.00 as a result of
-these two kernel threads:

-This fixes them to use interruptible sleep primitives while waiting in
-their main loops, as is conventional for kernel threads. They can't
-actually be interrupted since kernel threads ignore all signals, but
-by sleeping this way they get classified as long term waiters, and
-don't get counted as running for purposes of load average calculation.
-
-This is intended as a minimal fix. In the longer term, it'd probably
-make sense to replace the semaphores with completions or something,
-and to do away with some of these StudlyCapped wrapper functions.

-This is untested, but what could possibly go wrong? ;)
