2022-05-09nfs: fix broken handling of the softreval mount optionDan Aloni
Turns out that ever since this mount option was added, passing `softreval` in NFS mount options cancelled all other flags while not affecting the underlying flag `NFS_MOUNT_SOFTREVAL`.

This adds the overflow processing for large CQE's. This adds two parameters to the io_cqring_event_overflow function and uses these fields to initialize the large CQE fields. Allocate enough space for large CQE's in the overflow structue. If no large CQE's are used, the size of the allocation is unchanged. The cqe field can have a different size depending if its a large CQE or not. To be able to allocate different sizes, the two fields in the structure are re-ordered.

Normal SQEs are 64-bytes in length, which is fine for all the commands we support. However, in preparation for supporting passthrough IO, provide an option for setting up a ring with 128-byte SQEs. We continue to use the same type for io_uring_sqe, it's marked and commented with a zero sized array pad at the end. This provides up to 80 bytes of data for a passthrough command - 64 bytes for the extra added data, and 16 bytes available at the end of the existing SQE. Signed-off-by: Jens Axboe <axboe@kernel.dk>

2022-05-09io_uring: don't clear req->kbuf when buffer selection is doneJens Axboe

2022-05-09io_uring: eliminate the need to track provided buffer ID separatelyJens Axboe
We have io_kiocb->buf_index which is used for either fixed buffers, or for provided buffers. For the latter, it's used to hold the buffer group ID for buffer selection. Post selection, req->kbuf->bid is used to get the buffer ID. Store the buffer ID, when selected, in req->buf_index. If we do end up recycling the buffer, reset it back to the buffer group ID.

2022-05-09io_uring: get rid of hashed provided buffer groupsJens Axboe
Use a plain array for any group ID that's less than 64, and punt anything beyond that to an xarray. 64 fits in a page even for 4KB page sizes and with the planned additions. This makes the expected group usage faster by avoiding a hash and lookup to find our list, and it uses less memory upfront by not allocating any memory for provided buffers unless it's actually being used.

2022-05-09io_uring: always use req->buf_index for the provided buffer groupJens Axboe
The read/write opcodes use it already, but the recv/recvmsg do not. If we switch them over and read and validate this at init time while we're checking if the opcode supports it anyway, then we can do it in one spot and we don't have to pass in a separate group ID for io_buffer_select().

2022-05-09mtd: spi-nor: support eon en25qh256a variantLeon M. George
This patch allows accessing the upper 16m on the A variant (EN25QH256A) of the EN25QH256 that shares same JEDEC ID. Without this patch, addr_with is detected to be '4' but the read_opcode is a plain READ (supporting only 3 byte addresses). Setting PARSE_SFDP is enough to detect the read_opcode READ_4B on the A variant. READ_4B is not available on the no-A variant. Both variants support 4-byte address mode (spi_nor_set_4byte_addr_mode) but that is prone to breaking on unexpected reboots if the reset pin isn't connected (broken-flash-reset). The no-A variant supports a 'high bank latch mode' that affects read, program, and erase commands - similar to the extended address register (EAR). The HBL bit is manipulated using the ENHBL (0x67) and EXHBL (0x98) opcodes. Should it become necessary to distinguish the two variants in the future, the A variant sets the SNOR_HWCAPS_READ_1_1_4 SFDP param - the no-A variant doesn't. Tested with and without fast read on the A variant only. Signed-off-by: Leon M.

Also if you want to convert an existing flash chip to the new SFDP parsing, there is not enough information to determine if the flash will work like before. To ease this development, expose internal parameters via the debugfs.

2022-05-09m68k: Wire up syscall_trace_enter/leave for m68kMichael Schmitz
m68k (other than Coldfire) uses syscall_trace for both trace entry and trace exit. Seccomp support requires separate entry points for trace entry and exit which are already provided for Coldfire. Replace syscall_trace by syscall_trace_enter and syscall_trace_leave in preparation for seccomp support. No regression seen in testing with strace on ARAnyM.

Add a comma after each array value to make clang-format keep the current array formatting. See the following commit.

2022-05-09selftests/landlock: Add clang-format exceptionsMickaël Salaün
In preparation to a following commit, add clang-format on and clang-format off stanzas around constant definitions and the TEST_F_FORK macro. This enables to keep aligned values, which is much more readable than packed definitions. Add other clang-format exceptions for FIXTURE() and FIXTURE_VARIANT_ADD() declarations to force space before open brace, which is reported by checkpatch.pl .
