From: Jeffle Xu jefflexu@linux.alibaba.com Date: Tue, 2 Feb 2021 11:35:28 +0800 Subject: [PATCH] dm table: fix iterate_devices based device capability checks
According to the definition of dm_iterate_devices_fn: * This function must iterate through each section of device used by the * target until it encounters a non-zero return code, which it then returns. * Returns zero if no callout returned non-zero.
For some target type (e.g. dm-stripe), one call of iterate_devices() may iterate multiple underlying devices internally, in which case a non-zero return code returned by iterate_devices_callout_fn will stop the iteration in advance. No iterate_devices_callout_fn should return non-zero unless device iteration should stop.
Rename dm_table_requires_stable_pages() to dm_table_any_dev_attr() and elevate it for reuse to stop iterating (and return non-zero) on the first device that causes iterate_devices_callout_fn to return non-zero. Use dm_table_any_dev_attr() to properly iterate through devices.
Rename device_is_nonrot() to device_is_rotational() and invert logic accordingly to fix improper disposition.

The code this patch fixes, i.e., commit 200612ec33e5 ("dm table: propagate QUEUE_FLAG_NO_SG_MERGE"), was removed since commit 2705c93742e9 ("block: kill QUEUE_FLAG_NO_SG_MERGE") in v5.1. Thus the code base doesn't exist in the latest master branch.
Hi, Mike,
Would you please spare some time to review the following patches for stable tree?
- [1] for 4.4.y - [2] for 4.9.y - [3] for 4.14.y - [4] for 4.19.y
While backporting [5] for stable tree, there's some extra code specific to stable tree needs to be fixed, see [6] for the background info.

Sorry, it seems that this patch should not be separated from patch [5], as the NO_SG_MERGE capability check also calls dm_table_all_devices_attribute(), which has been removed in patch [5]. It will break the per-patch build-test when leave this patch not applied.
I will send a new version later. Please review on the new version directly.

Why only 4.4.y for these? What about all of the missing kernels in the middle (4.9, 4.14, 4.19, 5.4)? I can't apply fixes to one older branch and ignore others, as someone might upgrade and have a regression.
Please provide fixes for those other trees too, and then I will be glad to merge these.
