[PATCH 1/7] buffer: cleanup free_more_memory() flusher wakeup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This whole function is... interesting. Change the wakeup call
to the flusher threads to pass in nr_pages == 0, instead of
some random number of pages. This matches more closely what
similar cases do for memory shortage/reclaim.
