* Remove useless calls to basename().ed2016-05-011-2/+1
| | | | | | | | | | | | | | There are a couple of places in the source three where we call basename() on constant strings. This is bad, because the prototype standardized by POSIX allows the implementation to use its argument as a storage buffer. This change eliminates some of these unportable calls to basename() in cases where it was only added for cosmetical reasons, namely to trim argv[0]. There's nothing wrong with setting argv[0] to the full path. Reviewed by: jilles Differential Revision: https://reviews.freebsd.org/D6093

* Add 'devctl delete' that calls device_delete_child().jhb2016-04-273-2/+36
| | | | | | | | | | | | | 'devctl delete' can be used to delete a device that is no longer present. As an anti-foot-shooting measure, 'delete' will not delete a device unless it's parent bus says it is no longer present. This can be overridden by passing the force ('-f') flag. Note that this command should be used with care. If a device is deleted that is actually present it can't be resurrected unless the parent bus device's driver supports rescans.

* A new implementation of the loader block cacheallanjude2016-04-188-103/+189
| | | | | | | | | | | | | | | | | The block cache implementation in loader has proven to be almost useless, and in worst case even slowing down the disk reads due to insufficient cache size and extra memory copy. Also the current cache implementation does not cache reads from CDs, or work with zfs built on top of multiple disks. Instead of an LRU, this code uses a simple hash (O(1) read from cache), and instead of a single global cache, a separate cache per block device. The cache also implements limited read-ahead to increase performance. To simplify read ahead management, the read ahead will not wrap over bcache end, so in worst case, single block physical read will be performed to fill the last block in bcache.
