[PATCH 4/5] block: add trace point when fdatasync fails

2021-04-15 Thread Daniel P . Berrangé
A flush failure is a critical failure scenario for some operations. For example, it will prevent migration from completing, as it will make vm_stop() report an error. Thus it is important to have a trace point present for debugging. Signed-off-by: Daniel P. Berrangé --- block/file-posix.c | 2 ++
