[PATCH 12/14] fs: implement kernel_read using __kernel_read

2020-05-27 Thread Christoph Hellwig
Consolidate the two in-kernel read helpers to make upcoming changes easier. The only difference are the missing call to rw_verify_area in kernel_read, and an access_ok check that doesn't make sense for kernel buffers to start with. Signed-off-by: Christoph Hellwig --- fs/read_write.c | 13 +
