adrian c46f73c7ae Implement a kqueue notification path for sendfile. ... This fires off a kqueue note (of type sendfile) to the configured kqfd when the sendfile transaction has completed and the relevant memory backing the transaction is no longer in use by this transaction. This is analogous to SF_SYNC waiting for the mbufs to complete - except now you don't have to wait. Both SF_SYNC and SF_KQUEUE should work together, even if it doesn't necessarily make any practical sense. This is designed for use by applications which use backing cache/store files (eg Varnish) or POSIX shared memory (not sure anything is using it yet!) to know when a region of memory is free for re-use. Note it doesn't mark the region as free overall - only free from this transaction. The application developer still needs to track which ranges are in the process of being recycled and wait until all pending transactions are completed.
