[PATCH 6.1 64/71] f2fs: allow to read node block after shutdown

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jaegeuk Kim <jaegeuk@xxxxxxxxxx>

commit e6ecb142429183cef4835f31d4134050ae660032 upstream.

If block address is still alive, we should give a valid node block even after
shutdown. Otherwise, we can see zero data when reading out a file.
