[PATCH 00/20] fix magic return value in btrfs-progs

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

 



This patchset tries to fix all the magic return value in btrfs-progs.
Most commands will have three kinds of return value:

0 success
1 usage of syntax errors

Exceptions come from balance/scrub/replace. For example, replace cancel
will return 2 if there is no operations in progress.

Some tools including(btrfsck,chunk-recover) since they are still under
development. Also we should update man page if these magic return values
have been corrected.

Any comments are welcome.

Notice: this patchset is based on David integration-20130902
