* Unbreak the build on strong-aligned architectures (arm, ia64).marcel2010-09-201-1/+1
| | | | | | | Casting from (char *) to (struct ufs1_dinode *) changes the alignment requirement of the pointer and GCC does not know that the pointer is adequately aligned (due to malloc(3)), and warns about it. Cast to (void *) first to by-pass the check.

In particular, describe the deferred deallocations issue with vm_map_unlock_and_wait(). Redo the implementation of vm_map_unlock_and_wait() so that it passes along the caller's file and line information, just like the other map locking primitives. Reviewed by: kib X-MFC after: r212824

| | | | | | | | | | | | it frees local locks correctly upon close. In order for nfsrv_localunlock() to work correctly, the lock can no longer be in the lockowner's stateid list. As such, nfsrv_freenfslock() has to be called before nfsrv_localunlock(), to get rid of the lock structure on the lockowner's stateid list.

System map entries cannot be backed by OBJT_VNODE objects, no need to defer deallocation for them. Map entries from user maps do not require the owner map for deallocation, and can be accumulated in the thread-local list for freeing when a user map is unlocked. Move the collection of entries for deferred reclamation into vm_map_delete(). Create helper vm_map_process_deferred(), that is called from locations where processing is feasible. Do not process deferred entries in vm_map_unlock_and_wait() since map_sleep_mtx is held. Reviewed by: alc, rstone (previous versions) Tested by: pho MFC after: 2 weeks

Change the way the TSO burst length calculation is done. While TSO could do bursts of 65535 bytes that can't be represented in ip_len together with the IP and TCP header. Account for that and use IP_MAXPACKET instead of TCP_MAXWIN as base constant (both have the same value of 64K). When more data is available prevent less than MSS sized segments from being sent during the current TSO burst. Add two more KASSERTs to ensure the integrity of the packets.
