isofs_readdir() allocates a temporary buffer with __get_free_page(). kmalloc() is a better API for such use and it also provides better scalability and more debugging possibilities. Replace use of __get_free_page() with kmalloc(). Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org> --- fs/isofs/dir.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
