Try to run as much of test which could run without delay_dev.

45e749493c cleanup: ensuring string is not NULL 
Coverity cannot see the string cannot be NULL so make it explicit.

76b42901c0 cache: ensure there is no NULL str 
Coverity is not smart enough to detect this case could never happen.

b1215b7f8c lvmlockd: enforce 64bit arithmetic 
Coverity suggest to stay on the 'safe' side and widen operators early
so 64bit offset is made from 64bit arithmentic.

32762e2a9c libdaemon: fix passing 32bit values for %d 
Since %d is now prohibited for its great confusion,
replace it with  FMTd64 and correctly converted int64_t
parameter.

36ee367343 libdaemon: prohibit use of %d for 64bit numbres 
Do not let pass %d and print internal error when found one.
Require all users to use  FMTd64 - it's seriously confusing.

0b5a75c9af lvmetad: restore use of FMTd64 
daemon_reply_simple() eats just 64bit numbers - so make it explicit.

7103012754 tests: update test to check for race better 
Use  delay_dev to slow down mirror sync so we could more
easily check for race and proper reject of parallel mirror
leg addition/reduction.

Also expose fail in mirror allocation of parallel leg.

ab4773671b tests: do not skip test when delay is missing 
Rather then skipping whole test - just do not use it.

Failing tests that have required delay need to deal with reality
and shell either check for HAVE_DM_DELAY and skip portion
of test or using should when needed.

84a9546869 dmsetup: cleanup warn for older compilers 
Older gcc somehow thinks there is a path of using
subcommand uninitilized.

So make it more obvious there is no such one.

846adadbcc cleanup: use code in place 
Pass const strings to printf(),

b1dab26be0 cleanup: coverity quiet 
While through all codepaths we never 'read' lock_id unless LCKF_CONVERT,
coverity cannot decrypt this.

As since it's usually better to pass in 'well-defined' data structures
preset lock_id to 0.

11151121aa cleanup: use fputs for plain strings 
Use fputs() when printing plain string,
easier then fprintf which needs to parse it.

Also check fd before close is >= 0 -
it is - but coverity fail to see it, so eliminate
this false-positive warning.

subLV name.

5c48ef993b cleanup: use NAME_LEN buffer instead of alloca 
Drop alloca and use NAME_LEN size to get implicit check
for max len of LV name.

2e04eee192 cleanup: do not test alloca for NULL 
alloca() never returns NULL.
In case stack is out-of-range the behaviour is undefined.

c542c18d2a cleanup: drop unneded assign

856e11e11c lv_manip: do not deref NULL for debug message

deref it in debug message.

fa1d730847 dev-type: fix TOCTOU order 
Doing 'stat' checking first and later opening is racy.
And since we do not really care about any 'status' info
here and we read 'sysfs' here - just drop whole 'stat()'
call and directly handle error from failing 'fopen()'.

80c3fb786c thin: fix error path mem leak 
Coverity: when parsing of thin-pool status would have failed,
it could have leaked memory pool and dmt struct.

3cadc1c87e libdm: add test for dm_task_get_message_response() 
Coverity notices dm_task_get_message_response() result should be
checked for NULL which should not be passed to dm_pool_strdup().

18fd0bd20c lvconvert: add extra check for existance of pointer 
Coverity here is not fully-in-picture - but please it
with validation of pointer which currently cannot be null,
since we always return at least empty string.

99def8f439 lvmetad: check for pointers not NULL 
Check for  arg_vgid_lookup and arg_name_lookup not being NULL.
Drop checking arg_vgid and arg_name for NULL since they
are already dereference earlier - thus mostly must be NOT NULL.

(If that would be possible larger rework of this function would be
required).

f66fe2c444 lvmetad: require meta_lookup 
Coverity: do not call update_pvid_to_vgid() with
meta_lookup == NULL since it is dereferencing it.

91bde0f4a1 lvmetad: check for allocation fail 
Coverity: missing check for root != NULL as this pointer is

297d6773af dmsetup: add missing checks for dm_stats_create() ret value
