Linux-cifs:
The file "file4" gets created when using the touch command, but the
error message "touch: setting times of `file4': Permission denied" is
returned.
Seems like it is having an issue with the utimensat() call to set the
timestamp? Why is this? How is it solved?
Thanks in advance for any assistance.
Tim
