: : :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(). : :-- :Poul-Henning Kamp FreeBSD coreteam member :phk@FreeBSD.ORG "Real hackers run -current on their laptop." 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. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
