As a side effect it is now possible to specify a timeout larger that (USHRT_MAX / 100) seconds. To keep code simple `so_linger' now represents a number of seconds with 0 meaning no timeout or 'infinity'. Yes, the 0 -> INFSLP API change makes conversions complicated as many timeout holders are still memset()'d.

Forced unmount expects that the list is empty after flushing, otherwise the kernel panics with "dangling vnode". As the write to disk can sleep, new vnodes may be inserted. If softdep is enabled, resolving the dependencies creates new dirty vnodes and inserts them to the list. To fix the panic, let insmntque() insert new vnodes at the tail of the list. Then vflush() will still catch them while traversing the list in forward direction. OK tedu@ millert@ visa@ Convert infinite sleeps to tsleep_nsec(9). 2020-01-08T15:03:10Z mpi mpi@openbsd.org 2020-01-08T15:03:10Z urn:sha1:9b55129e7defe32636e1f234bcd995d2206136ca ok bluhm@
