block: force noio scope in blk_mq_freeze_queue

2025-01-31T14:20:08Z

When block drivers or the core block code perform allocations with a frozen queue, this could try to recurse into the block device to reclaim memory and deadlock. Thus all allocations done by a process that froze a queue need to be done without __GFP_IO and __GFP_FS. Instead of tying to track all of them down, force a noio scope as part of freezing the queue. Note that nvme is a bit of a mess here due to the non-owner freezes, and they will be addressed separately.

Pull MTD updates from Miquel Raynal: "MTD changes: - There's been no major core change, just a bunch of driver related improvements. Amongst them the conversion to of_property_present() for non-boolean properties, the addition of the support for Fujitsu MB85RS128TY FRAM, a couple of improvements to the phram driver and the usual load of misc changes. Raw NAND changes: - A new controller driver, from Nuvoton, has been merged - Bastien Curutchet has contributed a series improving the Davinci controller driver, both on the organization of the code, but also on the performance side. The binding has also been converted to yaml, received a new OOB layout and now supports on-die ECC engines - The Qualcomm controller driver has been deeply cleaned to extract some parts of the code into a shared file with the Qualcomm SPI memory controller - Aside from these main changes, the Cadence binding has been converted to yaml, the brcmnand controller driver has received a small fix, otherwise some more minor changes have also made their way in SPI NAND changes: - The SPI NAND subsystem has seen a great improvement, with the advent of DTR operations (DDR operations, which may be extended to the address cycles).

ubi: ubi_get_ec_info: Fix compiling error 'cast specifies array type'

On risc V platform, there is a type conversion for the return value (unsigned long type) of __untagged_addr_remote() in function untagged_addr(). The compiler will complain when the parameter 'addr' is an array type: arch/riscv/include/asm/uaccess.h:33:9: error: cast specifies array type (__force __typeof__(addr))__untagged_addr_remote(current->mm, __addr) Fix it by converting the input parameter as a pointer.
