Actually, I still very much do not like using M_NOWAIT needlessly. I would much rather the solution for make_dev() be that the 1 or 2 places that need to do it with a mutex held instead queue a task to do the actual make_dev() in a taskqueue when no locks are held. This is basically what destroy_dev_sched() is doing. Perhaps a make_dev_sched() with a similar callback to be called on completion would be better. Having a device driver do all the work to setup the hardware only to fail to create a node in /dev so that userland can actually use it is pretty rediculous and useless. -- John Baldwin _______________________________________________ svn-src-all@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
