to recycle inodes after a destroy_dev() but not until all mounts have picked up the change. Add support for an overflow table for DEVFS inodes. The static table defaults to 1024 inodes, if that fills, an overflow table of 32k inodes is allocated. Both numbers can be changed at compile time, the size of the overflow table also with the sysctl vfs.devfs.noverflow. Use atomic instructions to barrier between make_dev()/destroy_dev() and the mounts. Add lockmgr() locking of directories for operations accessing or modifying the directory TAILQs. Various nitpicking here and there. |
