Subject: PR/43727 CVS commit: src/sys/ufs/ffs

 Module Name:   src
 Committed By:  pooka
 Date:          Mon Aug  9 15:50:13 UTC 2010
 Modified Files:
        src/sys/ufs/ffs: ffs_vfsops.c
 Log Message:
 Return error if we try to mount a file system with block size > MAXBSIZE.
 Note: there is a billion ways to make the kernel panic by trying
 to mount a garbage file system and I don't imagine we'll ever get
 close to fixing even half of them.  However, for this one failing
 gracefully is a bonus since Xen DomU only does 32k MAXBSIZE and
 the 64k MAXBSIZE file systems are out there (PR port-xen/43727).
 Tested by compiling sys/rump with CPPFLAGS+=-DMAXPHYS=32768 (all
 tests in tests/fs still pass).  I don't know how we're going to
 translate this into an easy regression test, though.  Maybe with
 a hacked newfs?
