In the UEFI context GUIDs are expected to be rendered in upper case. The patch uses the formerly unused bit 1 of the parameter str_format of function uuid_bin_to_str() to indicate if we need upper or lower case output. Function uuid_string() in vsprint.c is adjusted to correctly set the bit depending on the print format code. %pUb: 01020304-0506-0708-090a-0b0c0d0e0f10 %pUB: 01020304-0506-0708-090A-0B0C0D0E0F10 %pUl: 04030201-0605-0807-090a-0b0c0d0e0f10 %pUL: 04030201-0605-0807-090A-0B0C0D0E0F10 Up to this point only a diagnostic message in mount_ubifs() using '%pUB' is concerned by the change. Further patches are needed to adjust the UEFI subsystem. A unit test is provided inside the ut_print command. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
