Modified files:
sys/ufs/ffs ffs_vfsops.c
sys/ufs/ufs ufs_extern.h ufs_ihash.c
Log:
Remove lock from ffs_vget introduced by v1.24. Instead of locking the
vnode creation globaly, we allow processes to create vnodes concurently.
In case of concurent creation of vnode for the one ino, we allow processes
to race and then check who wins.
Assuming that concurent creation of vnode for same ino is really rare case,
this is belived to be an improvement, as it just allows concurent creation
of vnodes.
