[PATCH] mount.cifs: fix the conflict between rwpidforward and rw mount options

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Both these options are started with "rw" - that's why the first one
isn't switched on even if it is specified. Fix this by adding a length
check for "rw" option check.
