From 4086d3f61b6573f65ddc13fc375c0c7b0ac482a0 Mon Sep 17 00:00:00 2001 From: Hou Pengyang Date: Fri, 21 Apr 2017 12:41:48 +0000 Subject: f2fs: skip encrypted inode in ASYNC IPU policy Async request may be throttled in block layer, so page for async may keep WRITE_BACK for a long time. For encrytped inode, we need wait on page writeback no matter if the device supports BDI_CAP_STABLE_WRITES. This may result in a higher waiting page writeback time for async encrypted inode page. This patch skips IPU for encrypted inode's updating write.
