sys/miscfs/procfs procfs.h procfs_vfsops.c procfs_vnops.c
Log:
Fixed panic that resulted from mmaping files in kernfs and procfs. A
regular user could panic the machine with a simple "tail /proc/curproc/mem"
command. The problem was twofold: both kernfs and procfs didn't fill in
the mnt_stat statfs struct (which would later lead to an integer divide
fault in the vnode pager), and kernfs bogusly paniced if a bmap was
attempted.
