Subject: [PATCH v2 09/13] arm64: extable: use `ex` for `exception_table_entry`
Date: Tue, 19 Oct 2021 17:02:15 +0100	[thread overview]
Message-ID: <20211019160219.5202-10-mark.rutland@arm.com> (raw)
In-Reply-To: <20211019160219.5202-1-mark.rutland@arm.com>

Subsequent patches will extend `struct exception_table_entry` with more
fields, and the distinction between the entry and its `fixup` field will
become more important.

For clarity, let's consistently use `ex` to refer to refer to an entire
entry. In subsequent patches we'll use `fixup` to refer to the fixup
field specifically. This matches the naming convention used today in
arch/arm64/net/bpf_jit_comp.c.

There should be no functional change as a result of this patch.
