I've reworked the locking for the kernel linker to convert the existing kld_mtx to an sx lock and extend it's scope to cover all of the various linker-related data structures. I also changed the kernel linker API a bit to make it more amenable to locking in that I added a 'linker_file_foreach' that iterates over the list of linker files calling a supplied predicate function and made the functions to lookup a linker file by name or index private. This meant that the ndis and hwpmc code had to stop fondling the kernel linker internals. I also made the VFS Giant locking in ndis and the kernel linker conditional such that it only locks Giant for non-MPSAFE filesystems. I have runtested this patch a while back, but the ndis and hwpmc parts have only been compile tested. Please test. http://www.FreeBSD.org/~jhb/patches/kld.patch -- John Baldwin
