:Here is the most up-to-date version of pgrp/session lock (at Change 6700): : :http://people.FreeBSD.org/~tanimura/patches/pgrp10.diff.gz : :I would like to commit this on the next Sunday. Otherwise, my patch :would conflict with other patches, especially tty. : :-- :Seigo Tanimura <tanimura@r.dl.itc.u-tokyo.ac.jp> <tanimura@FreeBSD.org> Do you have any plans to get pgdelete() out from under Giant? That would allow leavepgrp(), doenterpgrp(), enterpgrp(), enterthispgrp(), setsid() (mostly) to be taken out from under Giant, and perhaps a few others. I was thinking of simply having a free list of sessions and process groups, locked by PGRPSESS_XLOCK(). pgdelete() would then not have to call FREE() and setsid() would almost always be able to pull a new structure of the appropriate free list and thus not have to obtain Giant for the MALLOC. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
