If dm_io() returned an error, callers that set a notify.fn and wanted it called on an error need to check the return value and call notify.fn themselves if it was -EINVAL but not if it was -EIO. None of them do this (granted, all the existing async_io users of dm_io call it in a way that is guaranteed to not return an error). Simplify the interface by never calling the notify.fn if dm_io returns an error. This works with the existing dm_io callers which check for an error and handle it using the same methods as the notify.fn. This also allows us to move the now equivalent num_regions checks out of sync_io() and async_io() and into dm_io() itself. Additionally, change async_io() into a void function, since it can no longer fail. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> |

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.
