Subject: [patch 44/95] checkpatch: update __attribute__((section("name"))) quote removal
Date: Tue, 15 Dec 2020 20:44:43 -0800 [thread overview]
Message-ID: <20201216044443.0bDd7RfZz%akpm@linux-foundation.org> (raw)
In-Reply-To: <20201215204156.f05ec694b907845bcfab5c44@linux-foundation.org>
From: Joe Perches <joe@perches.com>
Subject: checkpatch: update __attribute__((section("name"))) quote removal
commit 33def8498fdd ("treewide: Convert macro and uses of
__section(foo) to __section("foo")") removed the stringification of the
section name and now requires quotes around the named section.
Update checkpatch to not remove any quotes when suggesting conversion
of __attribute__((section("name"))) to __section("name")
Miscellanea:
o Add section to the hash with __section replacement
o Remove separate test for __attribute__((section
o Remove the limitation on converting attributes containing only
known, possible conversions. Any unknown attribute types are now
left as-is and known types are converted and moved before
__attribute__ and removed from within the __attribute__((list...)).
[joe@perches.com: eliminate the separate test below the possible conversions loop]
