* DESCRIPTION
* Testcase to check execve(2) sets errno to EMFILE correctly
*
* ALGORITHM
* Get the configured file descriptor table size. open(2) files to
fill
* up the file descriptor table. Once file descriptor table is full,
* an attempt to execve(2) any other executable fails with EMFILE.
is what the source description says. Can you please execute the test
against that kernel commit and share the results with/without commits ?
