Message

Anand Jain March 27, 2023, 9:53 a.m. UTC

A few items were identified that could be optimized and simplified in
wait_dev_flush() and wait_dev_flush().

Anand Jain (4):
  btrfs: move last_flush_error to write_dev_flush and wait_dev_flush
  btrfs: opencode check_barrier_error()
  Btrfs: change wait_dev_flush() return type to bool
  btrfs: use test_and_clear_bit() in wait_dev_flush()
