Konstantin Belousov c6d31b8306 AST: rework ... Make most AST handlers dynamically registered. This allows to have subsystem-specific handler source located in the subsystem files, instead of making subr_trap.c aware of it. For instance, signal delivery code on return to userspace is now moved to kern_sig.c. Also, it allows to have some handlers designated as the cleanup (kclear) type, which are called both at AST and on thread/process exit. For instance, ast(), exit1(), and NFS server no longer need to be aware about UFS softdep processing. The dynamic registration also allows third-party modules to register AST handlers if needed. There is one caveat with loadable modules: the code does not make any effort to ensure that the module is not unloaded before all threads processed through AST handler in it. In fact, this is already present behavior for hwpmc.ko and ufs.ko. I do not think it is worth the efforts and the runtime overhead to try to fix it.
