Merge tag 'vfs-6.8.iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs iov_iter cleanups from Christian Brauner:
"This contains a minor cleanup. The patches drop an unused argument
from import_single_range() allowing to replace import_single_range()
with import_ubuf() and dropping import_single_range() completely"
* tag 'vfs-6.8.iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
iov_iter: replace import_single_range() with import_ubuf()
iov_iter: remove unused 'iov' argument from import_single_range()
