kib 2007-01-04 17:39:17 UTC FreeBSD src repository Modified files: (Branch: RELENG_6) sys/dev/md md.c Log: MFC of rev. 1.164: - Conditionally acquire Giant in mdstart_vnode(), mdcreate_vnode(), and mddestroy() only if the file is from a non-MPSAFE fs. There, to accommodate for the vn_open() difference with HEAD, use VFS_LOCK_GIANT after vn_open (since vn_open(..., -1) assumes caller is not MP-safe). - No longer unconditionally hold Giant in the md kthread for vnode-backed kthreads. - Improve the handling of the thread exit race when destroying an md device. No objections from: jhb Revision Changes Path 1.153.2.7 +22 -28 src/sys/dev/md/md.c
