Chao Yu a33c150237 f2fs: fix avoid race between truncate and background GC ... Thread A Background GC - f2fs_setattr isize to 0 - truncate_setsize - gc_data_segment - f2fs_get_read_data_page page #0 - set_page_dirty - set_cold_data - f2fs_truncate - f2fs_setattr isize to 4k - read 4k <--- hit data in cached page #0 Above race condition can cause read out invalid data in a truncated page, fix it by i_gc_rwsem[WRITE] lock.
