The .o.d make targets in common.mak do not expect that
header files are generated by a make target. When a new header
file is generated, the .o.d targets will be rebuilt on the
next make invocation, because that new header file is then
detected, and is then treated as a new dependency of all .o.d
targets.

The util_scandir_* functions may return 0 or -1, in which case no vector
is allocated in libutil/util_scandir.c. util_ptr_vec_free, called by
util_scandir_free or directly from lschp.c and lsscm.c, does always
call free for the vector which might be not initialized.
Fix this by always initializing the vector with NULL in __scandir and
add some api hardening by checking the vector and count in
util_ptr_vec_free before iterating over the vector.
And update the comment for util_scandir to indicate that -1 may be
returned in error cases plus that the vector is initialized with NULL.

Unfortunately zdev hook already exists in Ubuntu, from an unrelated
project. ZFS uses zdev/zpool names, and ships a zdev hook to do ZFS
specific initialisation. It is available on s390x and thus results in
file-conflict upon installing both. Thus renaming this zdev hook to
s390-tools-zdev.

At the moment, if we specify the slot address of an NVMe device but
can't find the corresponding device node, the execution is terminated.
This is a bit harsh as the device node is rather optional and only
necessary to collect S.M.A.R.T. data. We should still be able to issue
the error reporting, even if we couldn't determine the device node.
Therefore, make sure the device node for NVMe devices is optional by
changing various error messages to warnings.
Change sysfs_get_slot_addr() to have a return value and work with that
accordingly.
Also make sure, that execution is terminated when a valid device node
was specified but no matching slot address was determined. The slot
address is necessary to issue the error reporting commands.

zpcictl is used to manage PCI devices on z Systems. In this first
version it is mainly used to handle erroneous PCI devices by changing
their state and make those changes known to the SE. Log data, such as
S.M.A.R.T. data for NVMe devices, is sent alongside those state changes.
The state change is issued by sending data via the PCI 'report_error'
sysfs attribute. It's a binary attribute which will cause the host to
send an Adapter Notification Event.

zipl currently uses the FIBMAP ioctl to map blocks for the bootloader;
on XFS, if FIBMAP is requested on a reflinked file, it will fail -
and FIBMAP returns 0 in this case, which is indistinguishable from a
hole. This causes boot to fail because the file is not mapped.
We can use the FIEMAP ioctl instead, which is able to map reflinked
files. While FIEMAP is able to map entire extents at once, here we
simply use it to obtain the mapping block-by-block so that it fits
in with the current FIBMAP calls.

With kernel 4.19 there comes an extension to the existing
AP bus which supports alternate zcrypt drivers. For details
about this see kernel patch "s390/zcrypt: AP bus support for
alternate driver(s)". So now lszcrypt displays the driver
name in verbose mode. As some of the information displayed
by lszcrypt was based on sysfs attributes, which are only
available when the default zcrypt driver is bound to the
device, this also needed some rework. If a sysfs attribute
is not available because of an alternate driver binding
(or no driver) a question mark is printed into the field.
Together with this a slight rework of the displayed information
has been done. The two columns for pending requests and pending
replies has been merged to one pending column and the column
sizes have been adjusted.

zdsfs writes output for --help and --version to stderr. This is
likely because zdsfs calls into a FUSE function for additional
usage output that also writes to stderr (prior to FUSE 3.0.0).
To be consistent with other s390-tools and GNU coding guide lines,
fix this by using stdout for zdsfs generated output, and by

The default bash setting have nullglob disabled so if
$SCSI_DEV/scsi_generic*
aka
/sys/bus/scsi/devices/*:*:*:*/scsi_generic*
does not match anything, it leaves the glob pattern unmodified and
SG_DEV=$(basename $SG_DEV/*)
results in the literal:
*
If $SG_INQ exists, it invoked sg_inq with more than the one allowed
positional argument for a SCSI generic device node:
sg_inq /dev/*
Causing error messages and the usage of sg_inq to land in $TAPE_SERIAL.
To not have to rely on the nullglob setting, explicitly check for the
existence of $SCSI_DEV/scsi_generic before evaluating
SG_DEV=$(basename $SG_DEV/*).
Also handle availability of sg_inq but absence of scsi_generic
individually to provide the user with a hint if only sg is missing.

If sysfs is not available or provides no match, fall back to proc-fs.
An alternative to "ls -1d ... | head -n1" would have been to use
