Subject: [PATCH 10/11] mm: remove compat_process_vm_{readv,writev}
Date: Mon, 21 Sep 2020 16:34:33 +0200	[thread overview]
Message-ID: <20200921143434.707844-11-hch@lst.de> (raw)
In-Reply-To: <20200921143434.707844-1-hch@lst.de>

Now that import_iovec handles compat iovecs, the native syscalls
can be used for the compat case as well.

Subject: [PATCH 10/11] mm: remove compat_process_vm_{readv,writev}
Date: Mon, 21 Sep 2020 14:34:33 +0000	[thread overview]
Message-ID: <20200921143434.707844-11-hch@lst.de> (raw)
In-Reply-To: <20200921143434.707844-1-hch@lst.de>

Now that import_iovec handles compat iovecs, the native syscalls
can be used for the compat case as well.

Subject: [PATCH 10/11] mm: remove compat_process_vm_{readv,writev}
Date: Mon, 21 Sep 2020 16:34:33 +0200	[thread overview]
Message-ID: <20200921143434.707844-11-hch@lst.de> (raw)
In-Reply-To: <20200921143434.707844-1-hch@lst.de>

Now that import_iovec handles compat iovecs, the native syscalls
can be used for the compat case as well.

Subject: [PATCH 10/11] mm: remove compat_process_vm_{readv,writev}
Date: Mon, 21 Sep 2020 16:34:33 +0200	[thread overview]
Message-ID: <20200921143434.707844-11-hch@lst.de> (raw)
In-Reply-To: <20200921143434.707844-1-hch@lst.de>

Now that import_iovec handles compat iovecs, the native syscalls
can be used for the compat case as well.
