Seen in a 'make silentallconfig' Single-depth WCHAN output (SCHED_NO_NO_OMIT_FRAME_POINTER) [Y/n/?] (NEW) ? Calculate simpler /proc//wchan values. If this option is disabled then wchan values will recurse back to the caller function. This provides more accurate wchan values, at the expense of slightly more scheduling overhead. If in doubt, say "Y". So if I say 'y', is that a request to disable it, or enable it? And what exactly do I get if I vote *against* 'more accurate wchan values'? Do I get everybody having the same wchan pointing somewhere in the scheduler code, because that's where __builtin_return_address() points? And please - a triple negative in the Kconfig variable name? This has gotta be a winner for poor taste in variable naming... --==_Exmh_1226372137_3458P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFJGPQpcC3lWbTT17ARAopSAJ0XS6rbGlYJEOT0l22zjG4sWPOXnwCfRdGe 9WiS0/T1LGKERGxE6mjZttM= =5QW/ -----END PGP SIGNATURE----- --==_Exmh_1226372137_3458P--
