The free OSR Learning Library has more than 50 articles on a wide variety of topics about writing and debugging device drivers and Minifilters. From introductory level to advanced. All the articles have been recently reviewed and updated, and are written using the clear and definitive style you've come to expect from OSR over the years.

I should remember this, but....
Is the FileName.Buffer of a file object valid in a mini-filters post-create? Not the file name itself, just the buffer, can it be presumed not-freed or invalid in any way related to this purpose?
E.g. will the buffer be the buffer set by the I/O manager (or some mini-filter above us for a name virtualization filter)?
What I am considering is replacing the file name, and passing the IRP_MJ_CREATE down the line, and not reparsing, so that I can free the buffer myself in the post-create to a lookaside list.
