lib/iov_iter: initialize "flags" in new pipe_buffer #92

Open

strlcat wants to merge 1 commit into starfive-tech:JH7110_VisionFive2_devel from strlcat:JH7110_VisionFive2_devel_PRdpipefix

strlcat commented Mar 27, 2023

The functions copy_page_to_iter_pipe() and push_pipe() can both allocate a new pipe_buffer, but the "flags" member initializer is missing.
