How to get lazy writer thread ID

NTFSD
1

Hi,

I am writting a file system filter dirver. I hope to pass throught all IRP generated
by lazy writer. I think knowing the ID of lazy writer thread is necessary to achieve this.

I search in deja.com, Mr Maxim S. Shatskih suggest to use CcInitializeCacheMap.
I also referenced the FASTFAT source codes, but still don’t know how to do this.

Any suggestions?

Thank you very much.

I’m not quite sure but I think that lazy write may have a pool of threads.
Or perhaps it uses some of threads from system thread pool (worker threads).

You may use IoGetTopLevelIrp to see if it’s a lazy writer request.
