tail(1) assumes that mmap(2) works on works on regular files. mmap(2) on the irregular regular files /proc/*/map returns success but doesn't work. The first access to the mmapped memory usually causes the kernel to printf messages like the following: vnode_pager: *** WARNING *** stale FS getpages No strategy for buffer at 0xf12828e8 : 0xf3877800: type VREG, usecount 4, writecount 0, refcount 0, flags (VOBJBUF) tag VT_PROCFS, type 11, pid 591, mode 124, flags 0 : 0xf3877800: type VREG, usecount 4, writecount 0, refcount 0, flags (VOBJBUF) tag VT_PROCFS, type 11, pid 591, mode 124, flags 0 vnode_pager_getpages: I/O read error vm_fault: pager read error, pid 2023 (tail) pid 2023 (tail), uid 15: exited on signal 11 Bruce To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
