linux-toradex.git/Documentation/core-api/xarray.rst, branch v4.20-rc3 Linux kernel for Apalis and Colibri modules xarray: Add range store functionality 2018-10-21T14:46:46+00:00 Matthew Wilcox willy@infradead.org 2018-08-15T18:13:29+00:00 0e9446c35a80931044b6d8d2d74a9cabd248539f This version of xa_store_range() really only supports load and store. Our only user only needs basic load and store functionality, so there's no need to do the extra work to support marking and overlapping stores correctly yet.
