Keep in mind that each patch should create an independent small functional change. This makes it easier to review the patch and verify that what you said you were going to do matches what the patch does. For example, if you separate out the style, whitespace, ordering of declarations into an initial first patch, then all that noise is removed when the reviewer goes to check to implementation of one of the features below. This is a large patch, and should most certainly be broken up into several smaller patches. Do cleanups first, followed by functional changes. This ordering ensure that when a "git blame" is used in the future to understand why a given line is what it is, the first hit will be a functional change, and not a cleanup. > --- > Changes since v1: > - Cosmetic style changes; whitespace, ordering of declarations and > #includes, remoted extra comas from sentinels Please make this a separate change, possibly more than one, depending on how many of these there are.

BTW, Linus's tree was updated to v4.20-rc5 98 minutes ago. This patch can still cleanly apply there, and on your char-misc-linus branch.

[PATCH] [REPOST for the char-misc-linus branch] Drivers: hv: vmbus: Offload the handling of channels to two workqueues
vmbus_process_offer() mustn't call channel->sc_creation_callback() directly for sub-channels, because sc_creation_callback() -> vmbus_open() may never get the host's response to the OPEN_CHANNEL message (the host may rescind a channel at any time, e.g. in the case of hot removing a NIC), and vmbus_onoffer_rescind() may not wake up the vmbus_open() as it's blocked due to a non-zero vmbus_connection.offer_in_progress, and finally we have a deadlock. The above is also true for primary channels, if the related device drivers use sync probing mode by default. And, usually the handling of primary channels and sub-channels can depend on each other, so we should offload them to different workqueues to avoid possible deadlock, e.g. in sync-probing mode, NIC1's netvsc_subchan_work() can race with NIC2's netvsc_probe() -> rtnl_lock(), and causes deadlock: the former gets the rtnl_lock and waits for all the sub-channels to appear, but the latter can't get the rtnl_lock and this blocks the handling of sub-channels. The patch can fix the multiple-NIC deadlock described above for v3.x kernels (e.g. RHEL 7.x) which don't support async-probing of devices, and v4.4, v4.9, v4.14 and v4.18 which support async-probing but don't enable async-probing for Hyper-V drivers (yet). The patch can also fix the hang issue in sub-channel's handling described above for all versions of kernels, including v4.19 and v4.20-rc4. So actually the patch should be applied to all the existing kernels, not only the kernels that have 8195b1396ec8.
