From 90b803e6fb6243922bff9ddd8a6205c17cb93b31 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Fri, 25 Sep 2015 19:34:50 -0700 Subject: f2fs: do not skip dentry block writes Previously, we skip dentry block writes when wbc is SYNC_NONE with no memory pressure and the number of dirty pages is pretty small. But, we didn't skip for normal data writes, which gives us not much big impact on overall performance. Moreover, by skipping some data writes, kworker falls into infinite loop to try to write blocks, when many dir inodes have only one dentry block. So, this patch removes skipping data writes.
