This commit is either just wrong, is was misrebased, or is just badly out of order. It introduces a use of cpupri_find, but the function is not defined until commit ea9b3c95b7c666d4658a139b88587269e5baa647 ("sched: use a 2-d bitmap for searching lowest-pri CPU") about 146 commits later ... --=20 Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/ --Signature=_Sat__17_May_2008_13_23_17_+1000_BJ_XqBx4TtI6ah_7 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFILk+rTgG2atn1QN8RAowNAJwOS0f381qcb7van0m8TWEMkLYXIQCdHzsC U0mvt0AtTUcWhAAW4+Zg/P0= =L2X1 -----END PGP SIGNATURE----- --Signature=_Sat__17_May_2008_13_23_17_+1000_BJ_XqBx4TtI6ah_7--
