Ian Dowse 9d580d7c5f Slow down the operation of background fsck so as to leave some disk ... bandwidth for other processes. Since the sleeping is done from userland, this avoids the locking issues that affected the kernel version. The algorithm used here is to measure a moving average of the times taken by a sample of read operations and then delay 1 in 8 reads by 16 times the measured average. This should correspond to a factor of 3 slowdown, but in practice the factor is larger (3.5 to 4) due to hz rounding effects. Reviewed by: mckusick Approved by: re		2002-12-07 21:40:31 +00:00
