ipfilter 4.1.11 compile error: FreeBSD 5.4.p11, POLLOUTNORM undeclared

[N. Ersen SISECI]

Hello, 

I got the following error when i try to compile a new kernel with IPF 4.1.11 on FreeBSD 5.4-RELEASE-p11 after applying RWLOCK patch.

My kernel configuration is

options IPFILTER
options IPFILTER_LOG
options IPFILTER_SCAN
options IPFILTER_SYNC

mlfk_ipl.c:

304 #ifdef IPFILTER_SYNC
305                 if ((events & (POLLIN | POLLRDNORM)) && ipfsync_canread(xmin))
306                         revents |= events & (POLLIN | POLLRDNORM);
307                 if ((events & (POLLOUT | POLLWRNORM)) && ipfsync_canwrite(xmin))
308                         revents |= events & (POLLOUT | POLLOUTNORM);
309 #endif
