[PATCH 00/29] trivial adjustments for return variable coding style

[Anand Jain <anand.jain@oracle.com>]

Rename variable 'err'; instead, use 'ret', and the 'ret' helper variable
is renamed to 'ret2'.

https://btrfs.readthedocs.io/en/latest/dev/Development-notes.html#code

In functions where 'ret' is already used as a return helper (but not the
actual return), to avoid oversight, first rename the original 'ret'
variable to 'ret2', compile it, and then rename 'err' to 'ret'.
