On commit 39c90ece7565f5c47110c2fa77409d7a9478bd5b: [IPV4]: Convert rt_check_expire() from softirq processing to workqueue. we converted rt_check_expire() from softirq to workqueue, allowing the function to perform all work it was supposed to do. When the IP route cache is big, rt_check_expire() can take a long time to run. (default settings : 20% of the hash table is scanned at each invocation) Adding cond_resched() helps giving cpu to higher priority tasks if necessary. Using a "if (need_resched())" test before calling "cond_resched();" is necessary to avoid spending too much time doing the resched check. (My tests gave a time reduction from 88 ms to 25 ms per rt_check_expire() run on my i686 test machine) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.
