[Ocfs2-devel] [Bug] mmap fail for ocfs2-1.9.9 in 2.4.20
do the follow steps, on ext2, it is ok. but on ocfs2, it fails,
Test Steps:
1. Create a file, while it is open call unlink().
2. mmap the file to memory, then call close(). If mmap() add
extra reference to the file, the file descriptor will not be
removed.
3. Try to open the file, open should success;
3. munmap the mapped memory;
4. Try open the file again, should get ENOENT;
The result is in step 4, the file is still existing.

Create a file, while it is open call unlink().What sort of return code do you get from unlink? We don't support delete while a file is still open, so it's not surpise that the file is still there after all this -- we can't delete it! --Mark -- Mark Fasheh Software Developer, Oracle Corp mark.fasheh@oracle.com
