kib 52243403eb Move the head of byte-level advisory lock list from the ... filesystem-specific vnode data to the struct vnode. Provide the default implementation for the vop_advlock and vop_advlockasync. Purge the locks on the vnode reclaim by using the lf_purgelocks(). The default implementation is augmented for the nfs and smbfs. In the nfs_advlock, push the Giant inside the nfs_dolock. Before the change, the vop_advlock and vop_advlockasync have taken the unlocked vnode and dereferenced the fs-private inode data, racing with with the vnode reclamation due to forced unmount. Now, the vop_getattr under the shared vnode lock is used to obtain the inode size, and later, in the lf_advlockasync, after locking the vnode interlock, the VI_DOOMED flag is checked to prevent an operation on the doomed vnode. The implementation of the lf_purgelocks() is submitted by dfr. Reported by: kris Tested by: kris, pho Discussed with: jeff, dfr MFC after: 2 weeks		2008-04-16 11:33:32 +00:00
