* move the namecache_rb_tree from RB macros to RBT functions.dlg2016-09-161-2/+2
| | | | | | i had to shuffle the includes a bit. all the knowledge of the RB tree is now inside vfs_cache.c, and all accesses are via cache_* functions.

* all pools have their ipl set via pool_setipl, so fold it into pool_init.dlg2016-09-151-7/+5
| | | | | | | | | | | | | | | | | | | | | | the ioff argument to pool_init() is unused and has been for many years, so this replaces it with an ipl argument. because the ipl will be set on init we no longer need pool_setipl. most of these changes have been done with coccinelle using the spatch below. cocci sucks at formatting code though, so i fixed that by hand. the manpage and subr_pool.c bits i did myself. ok tedu@ jmatthew@ @ipl@ expression pp; expression ipl; expression s, a, o, f, m, p; @@ -pool_init(pp, s, a, o, f, m, p); -pool_setipl(pp, ipl); +pool_init(pp, s, a, ipl, f, m, p);

| | | | | | | | | | | | | | | | | | tested this with fuse _and_ drm on amd64 and macppc. Also tested with cloning bpf (not in the tree) on macppc. ok mikeb "looks correct to me" millert The original commit message is as follows: Increase size of the clone bitmap. A limit of only 64 device clones turned out to be too low for the upcoming work on cloning bpf. The new limit is 1024 device clones. As part of the size increase, the bitmap has been changed to be allocated separately to avoid bloating all device nodes, as suggested by guenther, millert and deraadt. ok millert mikeb

| | | | | | | | | | | | | problem pointed out by Martin Natano (natano (at) natano.net) Also, stop chaining assignments (foo = bar = baz) in vattr_null(). The exact meaning of those depends on the order of the sizes-and- signednesses of the lvalues, making them fragile: a statement here mixed *six* types, but managed to get them in a safe order. Delete a 20+ year old XXX comment that was almost certainly bemoaning a bug from when they were in an unsafe order. ok deraadt@ miod@

This way every consumer of the radix tree has a chance to explicitly initialize the shared data structures and no longer rely on another subsystem to do the initialization. As a bonus ``dom_maxrtkey'' is no longer used an die. ART kernels should now be fully usable because pf(4) and IPSEC properly initialized the radix tree. ok chris@, reyk@

* Stop using a shutdown hook for softraid(4) and explicitly shutdownmpi2014-07-101-1/+9
| | | | | | | | | | | | | | | | | | | the disciplines right after vfs_shutdown(). This change is required in order to be able to set `cold' to 1 before traversing the device (mainbus) tree for DVACT_POWERDOWN when halting a machine. Yes, this is ugly because sr_shutdown() needs to sleep. But at least it is obvious and hopefully somebody will be ofended and fix it. In order to properly flush the cache of the disks under softraid0, sr_shutdown() now propagates DVACT_POWERDOWN for this particular subtree of devices which are not under mainbus. As a side effect sd(4) shutdown hook should no longer be necessary. Tested by stsp@ and Jean-Philippe Ouellet. ok deraadt@, stsp@, jsing@

* While it may be smart to use the radix tree for exports it is not OK toclaudio2014-06-041-28/+28
| | | | | | | | | | use the domain specific tree initialisation method for this since that one is multipath enabled and assumes that the radix node is part of a struct rtentry. This code uses a different struct and so the multipath modifies wrong fields and breaks stuff in mysterious ways. Since we only support AF_INET here anyway simplify the code and only have one radix_node_head pointer instead of AF_MAX ones. Fixes NFS server issues reported by rpe@, OK rpe@, guenther@, sthen@
