[issue1472] panic: vnode_pager: vfs's must implement vop_getpages

New submission from Thomas Nikolajsen <[e-mail]>:

Running fsx (usr/src/test/stress/fsx) on MFS gives immediate panic.

I=2Ee., when /tmp is mfs mount, this causes panic:
$ fsx /tmp/XXX

This is on recent DEVELOPMENT from August 27;
it works on DEVELOPMENT kernel from July 29.

Core dump avail on request.

vop_getpages was removed from MFS in commit
8be7edadd39c45b84be3e3fb29cd8d2d0d853e16
