From 8c77bd62d6e4d68a70ba4baecb296b73ab252d2a Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Thu, 9 Apr 2020 10:25:21 -0700 Subject: [PATCH] f2fs: fix quota_sync failure due to f2fs_lock_op f2fs_quota_sync() uses f2fs_lock_op() before flushing dirty pages, but f2fs_write_data_page() returns EAGAIN. Likewise dentry blocks, we can just bypass getting the lock, since quota blocks are also maintained by checkpoint.
