close file descriptors and munmap pages.

Hi,

While executing the ltp on an nfs root mounted system, I faced a problem with some of the ltp test cases. These tests either did not close their file descriptors or did no unmap the mmaped files. This results in a failures while trying to clean up the temporary directory of the testcase.

Here are the failures I see.

I have fixed all of the above tests with the following patch.

Hi,

While executing the ltp on an nfs root mounted system, I faced a problem with some of the ltp test cases. These tests either did not close their file descriptors or did no unmap the mmaped files. This results in a failures while trying to clean up the temporary directory of the testcase.

Here are the failures I see.

Dear Subrata,

I downloaded the latest ltp from

I used the "snapshot" to download the tgz and patched as following.

The patch seems to apply correctly.

Please attach the patch as a file as well as inline. Some MTAs and
