https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276002 --- Comment #44 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Rick Macklem from comment #42) If the buffer size is 1M (shrug), then to map any page from this buffer, kernel would validate the whole buffer. At least this is the default setup where vfs.nfs.use_buf_pager is true. In other words, it should be not possible to have a buffer consisting of a single dirty page and rest of invalid pages. --=20 You are receiving this mail because: You are the assignee for the bug.=
