Author: araujo

New Revision: 320390
URL: https://svnweb.freebsd.org/changeset/base/320390

Log:
  With r318394 seems it breaks gpart(8) in some embedded systems such like PCEngines,
  RPI1-B, Alix and APU2 boards as well as NanoBSD with the following message:
  
  vnode_pager_generic_getpages_done: I/O read error 5
  
  Seems the breakage was because it was missed to include acr in glabel update.
