Subject: Re: [PATCH v4 16/23] iov_iter: introduce iov_iter_get_pages_[alloc_]flags()
Date: Tue, 21 Dec 2021 10:04:41 +0100 [thread overview]
Message-ID: <20211221090441.GC7949@lst.de> (raw)
In-Reply-To: <20211117215410.3695-17-logang@deltatee.com>
All these new helpers should be _GPL exports, keeping the existing

around GUP-fast) as out of line wrappers.
