SVN rev 202810 on 2010-01-22 14:44:15Z by jhb
MFC 193440,193442,193762,194019:
- Support shared vnode locks for write operations when the offset is
provided on filesystems that support it. This really improves mysql
+ innodb performance on ZFS.
- When checking for shared writes, use the struct mount returned from
vn_start_write.
- Simply shared vnode locking and extend it to also include fsync.
Also, in vop_write, no longer assert for exclusive locks on the
vnode.
- Stop asserting on exclusive locks in fsync since it can now support
shared vnode locking on ZFS.
