I' m developing a windows transparent encryption file system.
When implement the callback routines like create,read/write,cleanup,close,queryFileInformation and so on,I don't know which place should use which lock.
For convenience,I use a global locker like FltAcquireResourceExclusive(&global.lock) in every callback entrance and release lock after return ,then I found the system's performance efficiency is very low when open two or more files.
