Fix extract_user_to_sg() so that it will break out of the loop if iov_iter_extract_pages() returns 0 rather than looping around forever. [Note that I've included two fixes lines as the function got moved to a different file and renamed] Fixes:85dd2c8ff3("netfs: Add a function to extract a UBUF or IOVEC into a BVEC iterator") Fixes:f5f82cd187("Move netfs_extract_iter_to_sg() to lib/scatterlist.c") Signed-off-by: David Howells <dhowells@redhat.com> cc: Jeff Layton <jlayton@kernel.org> cc: Steve French <sfrench@samba.org> cc: Herbert Xu <herbert@gondor.apana.org.au> cc: netfs@lists.linux.dev Link: https://lore.kernel.org/r/1967121.1714034372@warthog.procyon.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
