probe.c (blkid_verify): Fix the bid_time sanity checking logic,
so that if last verification time is more recent than the
current time, or the comparison between the last
verification time and the current time causes an overflow,
a device verification will take place.
devname.c (blkid_get_dev): Set the initial bid_time to be
INT_MIN, to guarantee that blkid_verify will always be run
even when the system clock is insane.

The previous fix which fixed the problem with GNU make 3.81 building
all of the library object files caused GNU make 3.80 fail because the
subdirectories (such as elfshared) were not getting created. This fix
should allow the Makefiles to work with both GNU make 3.80 and GNU
make 3.81.
If the filesystem has an external journal, store the UUID of the
external journal in the tag EXT_JOURNAL.
If the filesystem type has changed, clear all the tags on the device,
not just a preset list of LABEL, UUID, TYPE, and SEC_TYPE.
Fix a bug so that blkid_set_tag will work correctly when freeing a tag
when the input name parameter comes from the tag that we are freeing.

Hello Ted,
here is a minor fixup with debugfs "icheck" finding a block in an EA.
It was reporting the inode number as one too low because it was set

On systems where is multi-path storage device is problem with duplicated
filesystems. The solution is select "the best" device. This is possible
by device-mapper library.
Short quotation from RH bugzilla:
With my patch, all dm devices remains in libblkid cache.
Only the top level dm devices are given high priority
and more appropriate node names (i.e. /dev/mapper/*) are used.
For example, if we have linear mapped dm device "ov1" over
dm device "disk1p3" which is multipath mapped to /dev/sdd3 and /dev/sdh3:
# dmsetup.static ls --tree
ov1 (253:5) <-- /dev/mapper/ov1 or /dev/dm-5
`-disk1p3 (253:4) <-- /dev/mapper/disk1p3 or /dev/dm-4
`-disk1 (253:0)
|- (8:112) <-- /dev/sdh
`- (8:48) <-- /dev/sdd
Original version of blkid will show:
# ./orig/blkid -t LABEL=mpdisk1p3 -l
/dev/sdd3: LABEL="mpdisk1p3" ... TYPE="ext3"
With my patch, blkid will show:
# ./deptree/blkid -t LABEL=mpdisk1p3 -l
/dev/mapper/ov1: LABEL="mpdisk1p3" ... TYPE="ext3"
In blkid cache, all devices are listed:
# ./orig/blkid -t LABEL=mpdisk1p3
/dev/sdd3: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/sdh3: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/dm-4: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/dm-5: LABEL="mpdisk1p3" ... TYPE="ext3"
# ./deptree/blkid -t LABEL=mpdisk1p3
/dev/mapper/ov1: LABEL="mpdisk1p3" ... TYPE="ext3"
/dev/sdd3: LABEL="mpdisk1p3" ... TYPE="ext3"

What's happening is that when you run on battery, e2fsck will delay
running the filesystem check, on the assumption that it is better to
defer the check until some time in the future when your laptop is
running on AC mains again. This deferral is not infinite, however; if
the number of mounts exceeds twice the max mount counts, or if the
interval between checks exceeds twice the check interval, e2fsck will
force the check even though you are on battery.
I've changed the sources to print a message to make this more clear.

This also changes syntax accepted by the profile parser. The value of
profile relations must not contain spaces unless it is quoted;
otherwise the parser will throw an error. Previously something like
this was allowed:
[liboptions]
test = foo bar
Now, the relation must be in double quotes in order to be valid, i.e.,
"foo bar".
Comments are allowed anywhere and can be started with either a ';' or
a '#' character. The only place where comments will not be intepreted
as beginning a comment is in a quoted string.

Add the ability for the e2fsck configuration file to override the
behaviour of e2fsck when a particular filesystem problem is
encountered. This allows reconnecting an inode to lost+found to not
stop the boot sequence, if a system administrator really badly wants
this behaviour for some specialized reason, for example.

The profile library was originally written by Theodore Ts'o in 1995
for use in the MIT Kerberos v5 library. It has been
modified/enhanced/bug-fixed over time by other members of the MIT
Kerberos team. This version was originally taken from the Kerberos
v5 distribution, version 1.4.2, and radically simplified for use in
e2fsprogs. (Support for locking for multi-threaded operations,
being able to modify and update the configuration file
programmatically, and Mac/Windows portability have been removed.
It has been folded into a single C source file to make it easier to
fold into an application program.)
