Subject: [PATCH v7 08/10] fs: update do_*() helpers to return ints
Date: Tue,  6 Jul 2021 19:48:59 +0700	[thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>

Update the following to return int rather than long, for uniformity with
the rest of the do_* helpers in namei.c:

* do_rmdir()
* do_unlinkat()
* do_mkdirat()
* do_mknodat()
* do_symlinkat()
