Subject: t_truncate_self: describe self better in error message
X-Git-Tag: v2022.05.01~2317
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=93d72ed7f6625958b4dccb12a42cd6953b08fbf9;p=users%2Fhch%2Fxfstests-dev.git

t_truncate_self: describe self better in error message

Include the name of the program that is trying to trucate itself
to error messages to distinguish between output for different
test cases (e.g. test_lower and test_upper in overlay/013).
