fs/ntfs3: Do not use driver own alloc wrappers
Problem with these wrapper is that we cannot take off example GFP_NOFS flag. It is not recomended use those in all places. Also if we change one driver specific wrapper to kernel wrapper then it would look really weird. People should be most familiar with kernel wrappers so let's just use those ones. Driver specific alloc wrapper also confuse some static analyzing tools, good example is example kernels checkpatch tool. After we converter these to kernel specific then warnings is showed. Following Coccinelle script was used to automate changing. virtual patch @alloc depends on patch@ expression x; expression y; @@ ( - ntfs_malloc(x) + kmalloc(x, GFP_NOFS) | - ntfs_zalloc(x) + kzalloc(x, GFP_NOFS) | - ntfs_vmalloc(x) + kvmalloc(x, GFP_NOFS) | - ntfs_free(x) + kfree(x) | - ntfs_vfree(x) + kvfree(x) | - ntfs_memdup(x, y) + kmemdup(x, y, GFP_NOFS) ) Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>
