H A D | coredump.c | 5456ffde Tue May 05 05:12:52 CDT 2020 Christoph Hellwig <hch@lst.de> powerpc/spufs: simplify spufs core dumping
Replace the coredump ->read method with a ->dump method that must call dump_emit itself. That way we avoid a buffer allocation an messing with set_fs() to call into code that is intended to deal with user buffers. For the ->get case we can now use a small on-stack buffer and avoid memory allocations as well.
