cifs: Mangle string used for unc in /proc/mounts
The string for "unc=" in /proc/mounts needs to be escaped. The current behaviour can create problems in cases when mounting a share starting with a number. example: >mount -t cifs -o username=test,password=x vm140-31:/17000-test /mnt >mount -o remount,password=x /mnt mount error: could not resolve address for vm140-31x00-test: Unknown error The sub-string "\170" which is part of the unc for the mount above in /proc/mounts is interpreted as character'x' in the case above. Escaping the string fixes the problem. Signed-off-by: Sachin Prabhu <sprabhu@redhat.com> Reviewed-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
