[PATCH fstests] generic/126: run it inside its own subdirectory

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



I had been seeing some failures in generic/126 when running on NFS under
kdevops.

The problem turned out to be that kdevops makes the root of the NFS
export mode 01777 by default (i.e. with the sticky bit set). This causes
some of these permission tests to fail because the open() is called with
the O_CREAT bit set.

Make the outcome of this test not depend on the permissions on
$TEST_DIR. Create a new directory to do these tests in, and clean it up
when done.
