This function is internal to systemd code, so external users of libudev
will not see those log messages. I think this is better. If we want to
allow that, the function could be put in libudev and exported.
v2: check that the string is more than one char before stripping quotes
The way the kernel namespaces have been implemented breaks assumptions
udev made regarding uevent sequence numbers. Creating devices in a
namespace "steals" uevents and its sequence numbers from the host. It
confuses the "udevadmin settle" logic, which might block until util a
timeout is reached, even when no uevent is pending.
Remove any assumptions about sequence numbers and deprecate libudev's
API exposing these numbers; none of that can reliably be used anymore
when namespaces are involved.
Emacs C indenting really gets confused by these lines if they carry no
trailing semicolon, hence let's make this nicer for good old emacs. The
other macros which define functions already do this too, so let's copy
the scheme here.
Also, let's use an uppercase name for the macro. So far our rough rule
was that macros that are totally not function-like (like this ones,
which define a function) are uppercase. (Well, admittedly it is a rough
rule only, for example function and variable decorators are all
lower-case SINCE THE CONSTANT YELLING IN THE SOURCES WOULD SUCK, and
also they at least got underscore prefixes.) Also, the macros that
define functions that we already have are all uppercase, so let's do the
same here...
