Linux: Fix tst-copy_file_range-large test on recent kernels [BZ #33498]HEADmaster
Instead of a negative return value the fixed FUSE copy_file_range will silently truncate the size to UINT_MAX & PAGE_MASK [1]. Allow that value to be returned as well. [1] https://github.com/torvalds/linux/commit/1e08938c3694f707bb165535df352ac97a8c75c9 Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
