From d7b8b384b02f52b20a538e741c75c5d50c0e131f Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Wed, 21 Oct 2015 18:49:50 -0700 Subject: [PATCH] f2fs: fix leakage of inmemory atomic pages If we got failure during commit_atomic_write, abort_volatile_write will be called, but will not drop the inmemory pages due to no FI_ATOMIC_FILE. Actually, there is no reason to check the flag in abort_volatile_write.
