      f2fs: avoid hungtask when GC encrypted block if io_bits is set · a9d572c7
      Sheng Yong 提交于
      When io_bits is set, GCing encrypted block may hit the following hungtask.
      Since io_bits requires aligned block address, f2fs_submit_page_write may
      return -EAGAIN if new_blkaddr does not satisify io_bits alignment. As a
      result, the encrypted page will never be writtenback.
      
      This patch makes move_data_block aware the EAGAIN error and cancel the
      writeback.

      f2fs: fix to drop all inmem pages correctly · a2e2e76b
      Chao Yu 提交于
      In commit 57864ae5 ("f2fs: limit # of inmemory pages"), we have
      limited memory footprint of all inmem pages with 20% of total memory,
      otherwise, if we exceed the threshold, we will try to drop all inmem
      pages to avoid excessive memory pressure resulting in performance
      regression.
      
      But in some unrelated error paths, we will also drop all inmem pages,
      which should be wrong, fix it in this patch.

      This patch introduces a new ioctl F2FS_IOC_PRECACHE_EXTENTS to precache
      extent info like ext4, in order to gain better performance during
      triggering AIO by eliminating synchronous waiting of mapping info.
