Hi,
Looks like this commit breaks 32bit/i386 systems:

libblkid: use mmap() rather than read()
----
libblkid/src/probe.c:638: mmap_buffer: Assertion `map_off + map_len >= real_off + len' failed.
I can avoid that assert if I change the type of map_len in blkid_bufinfo().
- size_t map_len;
+ blkid_loff_t map_len;
but it still looks broken, see this debug output
libblkid: LOWPROBE: --> starting probing loop [SUBLKS idx=-1]
libblkid: LOWPROBE: [0] linux_raid_member:
libblkid: LOWPROBE: call probefunc()
libblkid: BUFFER: mapping end of the device
libblkid: BUFFER: mmap 0xf7321000: off=4112515072, len=25771900928 (6291968 pages)
^^^^^^^
shouldn't we only mmap about 2M?
libblkid: BUFFER: reuse 0xf7321000: off=4112515072 len=25771900928 (for off=29884407808 len=256)
libblkid: BUFFER: mapping begin of the device
libblkid: BUFFER: mmap 0xf7121000: off=0, len=2097152 (512 pages)
libblkid: BUFFER: reuse 0xf7121000: off=0 len=2097152 (for off=4096 len=256)
cu,
Rudi
