svn commit: r196274 - head/sys/dev/usb

[Andrew Thompson]

Author: thompsa
Date: Sun Aug 16 14:13:55 2009
New Revision: 196274
URL: http://svn.freebsd.org/changeset/base/196274

Log:
  Change the usb workers from kernel processes to threads, this is mostly a
  cosmetic change to reduce cruft in the proc table.
  
  Also change the idle wait message to `-` like how taskqueues are.
