Subject: Clean-up: clang-tidy autofixes to eventfd and file-descriptor
X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=b4853cf42d4edb25351a1c772961534ecae458c2

Clean-up: clang-tidy autofixes to eventfd and file-descriptor

eventfd must be marked explicit to prevent erroneous implicit
conversions.

A destructor is provided since other special member functions are
defined (see cppcoreguidelines-special-member-functions).

file_descriptor's constructor is replaced by a trivial constructor.
