[PATCH 2/7] fuse: Change remove_from_page_cache

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

 



This patch series changes remove_from_page_cache's page ref counting
rule. Page cache ref count is decreased in delete_from_page_cache.
So we don't need decreasing page reference by caller.
