2021-04-12dmaengine: idxd: Fix clobbering of SWERR overflow bit on writebackDave Jiang
Current code blindly writes over the SWERR and the OVERFLOW bits. Write back the bits actually read instead so the driver avoids clobbering the OVERFLOW bit that comes after the register is read.

2021-04-12mmc: core: Use userland specified timeout value for eMMC sanitizeBean Huo
As the density increases, the 4-minute timeout value for sanitize is no longer feasible. At the same time, devices of different densities have different timeout values, which makes it difficult to use a common timeout value. Therefore, let's pass down the userland-specified sanitize timeout value so it can be used.

2021-04-11io_uring: ctx-wide rsrc nodesPavel Begunkov
If we're going to ever support multiple types of resources we need shared rsrc nodes to not bloat requests, that is implemented in this patch. It also gives a nicer API and saves one pointer dereference in io_req_set_rsrc_node(). We may say that all requests bound to a resource belong to one and only one rsrc node, and considering that nodes are removed and recycled strictly in-order, this separates requests into generations, where generation are changed on each node switch (i.e. io_rsrc_node_switch()). The API is simple, io_rsrc_node_switch() switches to a new generation if needed, and also optionally kills a passed in io_rsrc_data. Each call to io_rsrc_node_switch() have to be preceded with io_rsrc_node_switch_start(). The start function is idempotent and should not necessarily be followed by switch. One difference is that once a node was set it will always retain a valid rsrc node, even on unregister. It may be a nuisance at the moment, but makes much sense for multiple types of resources. Another thing changed is that nodes are bound to/associated with a io_rsrc_data later just before killing (i.e. switching).

2021-04-11io_uring: move rsrc_put callback into io_rsrc_dataPavel Begunkov
io_rsrc_node's callback operates only on a single io_rsrc_data and only with its resources, so rsrc_put() callback is actually a property of io_rsrc_data. Move it there, it makes code much nicecr.

2021-04-11io_uring: encapsulate rsrc node manipulationsPavel Begunkov
io_rsrc_node_get() and io_rsrc_node_set() are always used together, merge them into one so most users don't even see io_rsrc_node and don't need to care about it. It helped to catch io_sqe_files_register() inferring rsrc data argument for get and set differently, not a problem but a good sign.

2021-04-11io_uring: use rsrc prealloc infra for files regPavel Begunkov
Keep it consistent with update and use io_rsrc_node_prealloc() + io_rsrc_node_get() in io_sqe_files_register() as well, that will be used in future patches, not as error prone and allows to deduplicate rsrc_node init.

2021-04-11io_uring: simplify io_rsrc_node_ref_zeroPavel Begunkov
Replace queue_delayed_work() with mod_delayed_work() in io_rsrc_node_ref_zero() as the later one can schedule a new work, and cleanup it further for better readability.

Keep resource related structs' and functions' naming consistent, in particular use "io_rsrc" prefix for everything.
