Hi Folks,

I am going through the implementation of the locking available in vfs for holding the write call for fraction of time to initialize the snapshot module.

Can somebody point me about the vn_lock function which is used by lots of syscall under bsd kernel.

Can we directly use the vn_lock function to lock the write calls?

Is there any reference document which will make me understand the functionality of simple_lock,simple_unlock,VOP_LOCK and VOP_UNLOCK under darwin kernel.

Basically, Filesystem in Darwin is like Filesytem in *BSD system, *BSD filesytem will are good reference for you. -- Hu Gang .-. /v\ // \\ Linux User /( )\ [204016] GPG Key ID ^^-^^ http://soulinfo.com/~hugang/hugang.asc _______________________________________________ Do not post admin requests to the list.
