The directio(3C) function on Solaris is supported on NFS and UFS while the majority of users should be on ZFS, which is a copy-on-write file system that implements transparent compression and therefore cannot support unbuffered I/O. Let us remove the call to directio() and simply treat innodb_flush_method=O_DIRECT in the same way as the previous default value innodb_flush_method=fsync on Solaris. Also, let us remove some dead code around calls to os_file_set_nocache() on platforms where fcntl(2) is not usable with O_DIRECT. On IBM AIX, O_DIRECT is not documented for fcntl(2), only for open(2).
