queueing up buffers and awakening the MFS server process to do the I/O, we do the I/O to the server process's address space directly using facilities provided by UVM. This makes it possible for buffers attempting to flush out while the MFS is being unmounted to actually do the I/O, where before it would fail if the server process wasn't in the MFS idle loop (i.e. had been signaled and was attempting to exit). Should fix kern/10122 (I can no longer reproduce the problem described in the PR when running with these changes), and any number of other MFS-related complaints made by people over time. |
