Comment tst-ofdlocks-compat expected failure in some Linux releases
As pointed out in a libc-alpha thread [1], the misc/tst-ofdlocks-compat
may fail in some specific Linux releases. This patch adds a comment
along with a link to discussion in the test source code.
No changes are expected.
* sysdeps/unix/sysv/linux/tst-ofdlocks-compat.c: Add a comment about
a kernel issue which lead to test failure in some cases.
