Re: Part III: The Ins & Outs of DebugFS
Michael Anderson   8/8/2012 3:09:00 PM
NO RATINGS
@GBr For debugfs, you'd need to allocate the maximum buffer size and leave it there.  Then you could have a size variable and the actual buffer as two separate values to handle the variable buffer part.  Or, you could use remap_pfn_range() in the kernel and mmap() from user-space to just map the buffer directly into the user's address space.  Debugfs is probably less prone to errors though.
