[Bug 262894] Kernel Panic (page fault) with 13.1-BETA2 in g_eli & httpd

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262894 --- Comment #28 from Mark Johnston <markj@FreeBSD.org> --- (In reply to Alexander Motin from comment #26) BTW, the loop in vdev_geom_fill_unmap_cb() looks wrong to me when (addr & PAGE_MASK) != 0. Suppose addr & PAGE_MASK is 2048 and len is 4096. Then we want two pages in the array, but it looks like the loop will exit after the first iteration. I think we need to set addr &= ~PAGE_MASK before the loop, or I am missing something. I'm not sure when non-page-aligned ABD buffers can arise in practice though. -- You are receiving this mail because: You are the assignee for the bug.
