Jaegeuk Kim 50c63009f6 f2fs: avoid an infinite loop in f2fs_sync_dirty_inodes ... If one read IO is always failing, we can fall into an infinite loop in f2fs_sync_dirty_inodes. This happens during xfstests/generic/475. [ 142.803335] Buffer I/O error on dev dm-1, logical block 8388592, async page read ...
