Change parameters to cifs_unlink to match the ones used in the generic VFS. Add some local variables to cut down on the amount of struct dereferencing that needs to be done, and eliminate some unneeded NULL pointer checks on the parent directory inode. Finally, rename pTcon to "tcon" to more closely match standard kernel coding style. Signed-off-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>
