Re: tests/ls/stat-free-colors.sh broken with glibc-2.22

[Roland McGrath]

That libc change was intended to be a pure refactoring and should not have
changed the behavior at all.  That it caused the extra stat is a bug (it's
a simple inverted test typo).

This is in the grey area of whether the bug was "user-visible", but a
performance regression that bubbles up to perceptibility seems like it
qualifies.  So please file a bug at https://sourceware.org/bugzilla
(you can assign it directly to address@hidden).

Unfortunately, I can't think of a way to write a real regression test for
this in the libc test suite.  We don't really do "external" things like
use strace to determine if a test passes.


Thanks,
Roland
