X-Bogosity: Ham, tests=bogofilter, spamicity=0.000000, version=1.2.4 Sender: owner-linux-mm@kvack.org Precedence: bulk X-Loop: owner-majordomo@kvack.org List-ID: List-Subscribe: List-Unsubscribe: Introduce mas_wr_store_type() which will set the correct store type based on a walk of the tree. mas_prealloc_calc() is also introduced to abstract the calculation used to determine the number of nodes needed for a store operation. In this change a call to mas_reset() is removed in the error case of mas_prealloc(). This is only needed in the MA_STATE_REBALANCE case of mas_destroy(). We can move the call to mas_reset() directly to mas_destroy(). Also, add a test case to validate the order that we check the store type in is correct. This test models a vma expanding and then shrinking which is part of the boot process.

all users of mas_store() enter with nodes already preallocated. Check for the MA_STATE_PREALLOC flag to decide whether to preallocate nodes within mas_store() rather than relying on future write helper functions to perform the allocations. This allows the write helper functions to be simplified as they do not have to do checks to make sure there are enough allocated nodes to perform the write.

Users of mas_store_prealloc() enter this function with nodes already preallocated. This means the store type must be already set. We can then remove the call to mas_wr_store_type() and initialize the write state to continue the partial walk that was done when determining the store type.
