[PATCH] btrfs-progs: add always option to restore's looping prompt

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

 



If you are using btrfs restore to try to recover a very large or
fragmented file, you may encounter _lots_ of prompts requiring
you to press 'y' to continue because we are looping a lot.

Add the option to press 'a', to supress these prompts for the rest
of the file.
