I have reverted that commit, and commit 42a20f86dc19 ("sched: Add wrapper for get_wchan() to keep task blocked") which follows it, for today. --=20 Cheers, Stephen Rothwell --Sig_/iea/yGZ+7Qs/j230w26yVX1 Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmFtEuIACgkQAVBC80lX 0GyLewf+JxIj44eOOvF0/ffEXEESx61ZtHmzjJJrILL8JDr5NJz3eQKe211B9IzM OqHEGZOTuFiJx0sp1hrOYFpeoi3Dm7ebVk7c5M2vQczwGBgfIT2R+y266Pfb30Ed zMdEH34D28vakMHb5Ts7yl9wevpPoA3/mJgxiAHCjWAH3xMwRAHUg9Oi8+NEXgF+ PctvZaxODWGhkQXYNmPmSdx1fPguUO2TDHtIjZwhfp/TYQLvCw8Pzwtd7q8Ar8sp Hf3tYgBaESppjPA4IFuablPhZXZKUUJclEYkLMEJKQ8H+fnWYS3EC5D/1m2uohjt eIuddEBm+qvm1nGwSGhUlq8VG2t3Sg== =0fe8 -----END PGP SIGNATURE----- --Sig_/iea/yGZ+7Qs/j230w26yVX1--
