Subject: [PATCH] tests: do not rely on creat syscall failing with ETXTBSY
For many years "creat" syscall used to fail with ETXTBSY when applied
to the running executable:
$ strace -v tests/creat
execve("tests/creat", ["tests/creat"], []) = 0
...
creat("tests/creat", 000) = -1 ETXTBSY (Text file busy)
...
Apparently, something has changed in Fedora Rawhide:
$ strace -v tests/creat
execve("tests/creat", ["tests/creat"], []) = 0
...
creat("tests/creat", 000) = 3

* tests/umode_t.c (sample): Change to ".".
* tests/gen_tests.in (creat, mkdir, mkdirat): Update -a option argument.
