970df59f91 cache: scan kallsyms for kernel symbols
With monolithic kernels we can't actually modprobe
for cache modules as they are already compiled-in
and policy modules do not export version symbol.

Reported issue on list:
https://www.redhat.com/archives/dm-devel/2017-March/msg00061.html

Fix will try to look for explicit kernel symbols first before
calling modprobe.

d6ddacf6a1 lvchange: persistent major/minor processing regression

(see starting commit 1e2420bca8)
causing activation to be rejected in combination with setting
persistent minor device numbers.

In case we provide a description file it has to
succeed opening and reading.  Dynamically allocate
buffer space for it whilst on it.

834574cc27 dmfilemapd: use log_sys_error in _filemap_monitor_set_notify
Since _filemap_monitor_set_notify() is only called after daemon
start up it should not use the _early_log() macros. Instead, use
log_sys_error to log errors from the two syscalls in the function.

fe0922b8a6 dmsetup: simplify branching in _stats_update_file()
The fallback branch in _stats_update_file() is redundant (since the
branch taken when the daemon starts successfully must jump to the
'out' label anyway): remove it and re-order the conditions to
improve readability.

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.
