Can anyone help me reason about the readpages() callback in vma_operations? Do the pages that come in the argument list from readahead come locked? The documentation in the kernel says nothing about locking on the way in (Documentation/filesystems/Locking) unlike readpage. It does say that the pages should be unlocked when the operation is done. Should I assume that the readpages implementer needs to take care to lock those pages her / his self? I've been reading through the code for different filesystems to understand what should happen but I'm not a 100% clear on it.
