Subject: [PATCH 3/3] cal: don't mix ncurses output functions and printf()
Fedora 18 (ncurses-libs-5.9-7.20121017, glibc-2.16-28):
$ cal | cat
Actual results:
January 2013 Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 8

Not sure where is the problem, but it's too fragile to mix two
output methods in one code.

From 2270b1ad90b394950f4fe215eb2fc1042020cef0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] libblkid: remove optimization from verify( funrtion
Now libblkid (the cache based part) tries to probe for the cached
filesystem firstly. This optimization is broken, because:
* new another superblock could be on the device and the original
is already obsolete
* we still need to probe for partitions and raids
* the code was too fragile
The patch also suggests lsblk --fs in blkid.8 for end users. lsblk
read information from used db.
