Since I_SYNC was split out from I_LOCK, the concern in commit 4b89eed9 ("Write back inode data pages even when the inode itself is locked") is not longer valid. We should revert to the original behavior: in __writeback_single_inode(), when we find an I_SYNC-ed inode and we're not doing a data-integrity sync, skip writing entirely. Otherwise, we are double calling do_writepages() Signed-off-by:
