- * FILE : lftest.c
- * DESCRIPTION : The purpose of this test is to verify the file size limitations of a filesystem.
- * It writes one buffer at a time and lseeks from the beginning of the file to the
- * end of the last write position. The intent is to test lseek64.
- * HISTORY:
- * 06/19/01 : Written by Jeff Martin(martinjn@us.ibm.com) to test large files on jfs.
- * 07/12/01 : Added timing.
