  log: "Pull up following revision(s) (requested by hannken in ticket #669):\n\n\tsys/dev/ccd.c:
    revision 1.190\n\nUsing a ccd(4) with GPT (dk* at ccd*) the disk framework will
    call\nccdstrategy() -> ccdstart() -> ccdbuffer()  from softint context.\n\nAllocating
    the buffer with PR_WAITOK here is forbidden.\n\nChange ccdstart() / ccdbuffer()
    to report failure back to caller and\npass PR_WAITOK / PR_NOWAIT as an additional
    argument.\n\nCall ccdstart() with PR_NOPWAIT from ccdstrategy() and on error defer\nto
    the kthread.  Call ccdstart() with PR_WAITOK from kthread so requests\nfrom kthread
    always succeed to allocate the buffers.\n\nRemove the (non working) throttling
    on low memory as it is no longer needed.\n\nFixes PR kern/58043 \"kernel crash
    in assert_sleepable() in -current,\ndk(4) driver?\"\n"
