Matt Johnston 72f53c5694 Revert part of "Log I/Os longer than zio_delay_max (30s default)" ... This reverts commit 9dcb971983 which was originally introduced to debug occasional slow I/Os. These I/Os would complete eventually but were observed to take several 100 seconds. The root cause of this issue was the CFQ scheduler which can, under certain conditions, excessively delay an I/O from being issued to the device. This issue was mitigated somewhat by commit 84daaddedb which ensures the I/O elevator gets changed even for DM style devices. This change isn't in any way harmful but it does conflict with a required change to properly account from I/O wait time. Because Linux does not export the io_schedule_timeout() function we must instead rely on io_schedule() via cv_wait_io(). The additional debugging information which was added to the delay event has been intentionally left in place. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov>		2013-01-07 10:51:04 -08:00
