From 26dc3d4424e9f4764d633bd8f9309a01e6f364dd Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Mon, 11 Apr 2016 13:15:10 -0700 Subject: [PATCH] f2fs: unset atomic/volatile flag in f2fs_release_file The atomic/volatile operation should be done in pair of start and commit ioctl. For example, if a killed process remains open-ended atomic operation, we should drop its flag as well as its atomic data. Otherwise, if sqlite initiates another operation which doesn't require atomic writes, it will lose every data, since f2fs still treats with them as atomic writes; nobody will trigger its commit.
