[PATCH] 2.2.18pre13: Small patches from Andrea

From: Chip Salzenberg (chip@valinux.com)
Date: Mon Oct 02 2000 - 16:26:53 EST


I suppose I should let Andrea submit these, but he has such a huge
patch collection (thank you!) that I thought it might be useful to
pick out some of the smaller ones that would be less controversial
for inclusion in the main kernel.

 * nanosleep-4
     Provide nanosleep usec resolution so that a signal flood doesn't hang
     glibc folks that correctly trust the rem field to resume the nanosleep
     after a syscall interruption. (without the patch nanosleep resolution
     is instead 10msec on IA32 and around 1msec on alpha)
 * tsc-calibration-non-compile-time-1
     TSC calibration must be dynamic and not a compile time thing because
     gettimeofday is dynamic and it depends on the TSCs to be in sync.
 * IO-wait-2
     Avoid spurious unplug of the I/O queue.
 * buf-run_task_queue
     Avoid spurious unplug of the I/O queue. (again!)
 * account-failed-buffer-tries-1
     Account also for failed buffer tries during shrink_mmap.
 * overcommit-1
     Make sure to not understimate the available memory (the cache and
     buffers may be under the min percent).
