From bdd1d2d3d251c65b74ac4493e08db18971c09240 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 1 Sep 2017 17:39:13 +0200 Subject: fs: fix kernel_read prototype Use proper ssize_t and size_t types for the return value and count argument, move the offset last and make it an in/out argument like all other read/write helpers, and make the buf argument a void pointer to get rid of lots of casts in the callers.
