Re: Proposed patch to fix VN device (again)

:Ahh, I see the mistake.

:All you need to fix this is to add a new function:
:
:       void
:       flushswchainbuf(struct buf *nbp)
:       {
:               if (nbp->b_bcount) {
:                       nbp->b_bufsize = nbp->b_bcount;
:                       if ((nbp->b_flags & B_READ) == 0)
:                               nbp->b_dirtyend = nbp->b_bcount;
:                       BUF_KERNPROC(nbp);
:                       swstrategy(nbp);
:               } else {
:                       biodone(nbp);
:               }
:       }
:
:And use this instead of flushchainbuf() in swap_pager_strategy().

    Uh... no.  The chain buffer routines are supposed to be generic.  In fact,
    all the filesystem buffer cache I/O routines are supposed to be generic.
    There is no way I'm going to pollute them to special case swap.
