Coleman Kane 5a22de144a Linux 6.5 compat: replace generic_file_splice_read with filemap_splice_read ... The generic_file_splice_read function was removed in Linux 6.5 in favor of filemap_splice_read. Add an autoconf test for filemap_splice_read and use it if it is found as the handler for .splice_read in the file_operations struct. Additionally, ITER_PIPE was removed in 6.5. This change removes the ITER_* macros that OpenZFS doesn't use from being tested in config/kernel-vfs-iov_iter.m4. The removal of ITER_PIPE was causing the test to fail, which also affected the code responsible for setting the .splice_read handler, above. That behavior caused run-time panics on Linux 6.5.
