sys/kern vfs_syscalls.c
sys/ufs/ffs ffs_vnops.c
contrib/sys/softupdates ffs_softdep.c
Log:
Eliminate a race in VOP_FSYNC() when softupdates is enabled.
Submitted by: Kirk McKusick <mckusick@McKusick.COM>
Two minor changes are also included,
1. Remove gratuitious checks for error return from vn_lock with LK_RETRY set,
vn_lock should always succeed in these cases.
2. Back out change rev. 1.36->1.37, which unnecessarily makes async mount
a little more unstable. It also keeps us in sync with other BSDs.
