nilfs_ioctl_wrap_copy() allocates a temporary buffer with get_zeroed_page(). kzalloc() is a better API for such use and it also provides better scalability and more debugging possibilities. Replace use of get_zeroed_page() with kzalloc(). Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org> --- fs/nilfs2/ioctl.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
