You may want to check NFS code that uses stack heavily. Here are numbers for i386 (bytes-on-stack, module, what function): 1344 nfs_nfsdport.o <nfssvc_nfsd>: 1152 nfs_nfsdserv.o <nfsrvd_lockt>: 1128 nfs_nfsdserv.o <nfsrvd_lock>: 952 nfs_nfsdserv.o <nfsrvd_rename>: 664 nfs_nfsdserv.o <nfsrvd_open>: 640 nfs_nfsdserv.o <nfsrvd_link>: 624 nfs_nfsdserv.o <nfsrvd_create>: 608 nfs_nfsdserv.o <nfsrvd_mknod>: 600 nfs_clvfsops.o <nfs_mount>: _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
