  "message": "[NET]: rt_check_expire() can take a long time, add a cond_resched()\n\nOn commit 39c90ece7565f5c47110c2fa77409d7a9478bd5b:\n\n\t[IPV4]: Convert rt_check_expire() from softirq processing to workqueue.\n\nwe converted rt_check_expire() from softirq to workqueue, allowing the\nfunction to perform all work it was supposed to do.\n\nWhen the IP route cache is big, rt_check_expire() can take a long time\nto run.  (default settings : 20% of the hash table is scanned at each\ninvocation)\n\nAdding cond_resched() helps giving cpu to higher priority tasks if\nnecessary.\n\nUsing a \"if (need_resched())\" test before calling \"cond_resched();\" is\nnecessary to avoid spending too much time doing the resched check.\n(My tests gave a time reduction from 88 ms to 25 ms per\nrt_check_expire() run on my i686 test machine)\n\nSigned-off-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nSigned-off-by: David S.
