Hm, I thought that sysfs binary files were supposed to be for "transparent" blobs of data, not for structured data. E.g., a "firmware" blob would be OK. And I'm looking at current users. ISTM that this one: arch/ppc/syslib/mv64x60.c:2443: sysfs_create_bin_file(&mv64xxx_device.dev.kobj, &mv64xxx_hs_reg_attr); in its sysfs read function returns a string (binary data converted to a string) instead of returning binary data. Or did I misread it? or misunderstand sysfs binary data? --- ~Randy - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
