Replace cv_{timed}wait_sig with cv_{timed}wait_idle where appropriate
There are a number of places where cv_?_sig is used simply for accounting purposes but the surrounding code has no ability to cope with actually receiving a signal. On FreeBSD it is possible to send signals to individual kernel threads so this could enable undesirable behavior. This patch adds routines on Linux that will do the same idle accounting as _sig without making the task interruptible. On FreeBSD cv_*_idle are all aliases for cv_* Reviewed-by: Alexander Motin <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Matt Macy <[email protected]> Closes #10843
