4b3d71212f libdm: use log_sys_error if dmfilemapd exec fails
Use log_sys_error rather than log_error if execvp() fails:

  /mnt/redhat/xdoio.13752.XIORQ: Created new group with 2 region(s) as group ID 0.
  # execvp() failed.

vs:

  /var/lib/libvirt/images/rhel7-vm1.qcow2: Created new group with 884 region(s) as group ID 0.
  dmfilemapd: execvp failed: No such file or directory

f66bc3dab0 dmfilemapd: fix off-by-one in fd comparison (coverity)
The function _filemap_monitor_check_file_unlinked() attempts to
test whether a fd value should be closed by comparison to zero:

        if ((fd > 0) && close(fd))
                log_error("Error closing fd %d", fd);

The test should be '>=' since 0 is a valid file descriptor.

8658bbe3ee dmfilemapd: always close link check file descriptor (coverity)
Similar to 40fb91a, but for the file descriptor opened using the
link path reported by /proc/<self>/fd/<fd>.

The daemon opens a new file descriptor from /proc/<self>/fd when
checking for an unlinked file with mode=inode. Ensure that it is
always closed even if the same file test fails.

43fdbb8aeb dmfilemapd: use *argv[0] when testing for absolute path (coverity)
The path argument check in dmfilemapd incorrectly tests for:

  if (argv[0] == '/')

Rather than testing the 1st character in the string pointed to by
argv[0].

78d004efa8 build: fix x32 arch
This patch fixed lvm2 compilation running on x32 arch.
(Using 64bit x86 cpu features but running on 32b address space,
so consuming less mem in VM).

On x32 arch 'time_t' is 64bit while 'long' is 32bit.

36cac41115 man-generator/man/help: simplify hyphen escaping
Commits a29bb6a14b
    ... 5c199d99f4
narrowed down on addressing the escaping of hyphens
in the dynamic creation of manuals whilst avoiding
them in creating help texts.  This lead to a sequence
of slipping through hyphens adrressed by additional
patches in aforementioned commit series.

On the other hand, postprocessing dynamically man-generator
created and statically provided manuals catches all hyphens
in need of escaping.

Changes:
- revert the above commits whilst keeping man-generator
  streamlining and the detection of any '\' when generating
  help texts in order to avoid escapes to slip in

- Dynamically escape hyphens in manaual pages using sed(1)
  in the respective Makefile targets

- remove any manually added escaping on hyphens from any
  static manual sources or headers

6165e09221 lvchange: reject setting all raid1 images to writemostly
raid1 doesn't allow to set all images to writemostly because at
least one image is required to receive any written data immediately.

The dm-raid target will detect such invalid request and
fail it iwith a kernel error message.

Reject such request in uspace displaying a respective error message.

0dabe7237c commands: fix commands with run with path basename
The recent command definitions commit took the command
name from argv[0] without applying basename to the value,
so a pathname, e.g. /usr/sbin, would cause lvm to not
recognize the command name.

b84bf3e8cd raid: adjust to misordered raid table line output
This commit supersedes reverted 1e4462dbfb
to avoid changes to liblvm and the libdm API completely.

The libdevmapper interface compares existing table line retrieved from
the kernel to new table line created to decide if it can suppress a reload.
Any difference between input and output of the table line is taken to be a
change thus causing a table reload.

The dm-raid target started to misorder the raid parameters (e.g. 'raid10_copies')
starting with dm-raid target version 1.9.0 up to (excluding) 1.11.0.  This causes
runtime failures (limited to raid10 as of tests) and needs to be reversed to allow
e.g. old lvm2 uspace to run properly.

Check for the aforementioned version range in libdm and adjust creation of the table line
to the respective (mis)ordered sequence inside and correct order outside the range
(as described for the raid target in the kernels Documentation/device-mapper/dm-raid.txt).
