These can be shared with all kernel ULPs, and more can easily be added as needed. Note: checkpatch.pl has some heartburn with the TRACE_DEFINE_ENUM macros and the LIST macros. These follow the same style as other header files under include/tracing/events , thus should be considered acceptable exceptions.

Clean up: struct rpcrdma_mw was named after Memory Windows, but xprtrdma no longer supports a Memory Window registration mode. Rename rpcrdma_mw and its fields to reduce confusion and make the code more sensible to read. Renaming "mw" was suggested by Tom Talpey, the author of the original xprtrdma implementation. It's a good idea, but I haven't done this until now because it's a huge diffstat for no benefit other than code readability. However, I'm about to introduce static trace points that expose a few of xprtrdma's internal data structures. They should make sense in the trace report, and it's reasonable to treat trace points as a kernel API contract which might be difficult to change later. While I'm churning things up, two additional changes: - rename variables unhelpfully called "r" to "mr", to improve code clarity, and - rename the MR-related helper functions using the form "rpcrdma_mr_<verb>", to be consistent with other areas of the code.

Clean up: Over time, the industry has adopted the term "frwr" instead of "frmr". The term "frwr" is now more widely recognized. For the past couple of years I've attempted to add new code using "frwr" , but there still remains plenty of older code that still uses "frmr". Replace all usage of "frmr" to avoid confusion. While we're churning code, rename variables unhelpfully called "f" to "frwr", to improve code clarity.

No need for the overhead of atomically setting and clearing this bit flag for every use of a pre-allocated backchannel rpc_rqst. These are a distinct pool of rpc_rqsts that are used only for callback operations, so it is safe to simply leave the bit set.

Clean up. @rqst is set up differently for backchannel Replies. For example, rqst->rq_task and task->tk_client are both NULL. So it is easier to understand and maintain this code path if it is separated. Also, we can get rid of the confusing rl_connect_cookie hack in rpcrdma_bc_receive_call.

Since commit 5a6d1db4 ("SUNRPC: Add a transport-specific private field in rpc_rqst"), the rpc_rqst's for RPC-over-RDMA backchannel operations leave rq_buffer set to NULL. xprt_release does not invoke ->op->buf_free when rq_buffer is NULL. The RPCRDMA_REQ_F_BACKCHANNEL check in xprt_rdma_free is therefore redundant because xprt_rdma_free is not invoked for backchannel requests.

Clean up a harmless oversight. xprtrdma's ->set_port method has never properly supported IPv6.

The backchannel code uses rpcrdma_recv_buffer_put to add new reps to the free rep list. This also decrements rb_recv_count, which spoofs the receive overrun logic in rpcrdma_buffer_get_rep. Commit 9b06688b ("xprtrdma: Fix additional uses of spin_lock_irqsave(rb_lock)") replaced the original open-coded list_add with a call to rpcrdma_recv_buffer_put(), but then a year later, commit 05c97466 ("xprtrdma: Fix receive buffer accounting") added rep accounting to rpcrdma_recv_buffer_put. It was an oversight to let the backchannel continue to use this function. The fix this, let's combine the "add to free list" logic with rpcrdma_create_rep. Also, do not allocate RPCRDMA_MAX_BC_REQUESTS rpcrdma_reps in rpcrdma_buffer_create and then allocate additional rpcrdma_reps in rpcrdma_bc_setup_reps. Allocating the extra reps during backchannel set-up is sufficient.

This leak has been around forever, and is exceptionally rare. EINVAL causes mount to fail with "an incorrect mount option was specified" although it's not likely that one of the mount options is incorrect. Instead, return ENODEV in this case, as this appears to be an issue with system or device configuration rather than a specific mount option. Some obsolete comments are also removed.

However, since that no longer zeroes the mapped pages, it is not suitable for KASAN, which requires zeroed shadow memory. Add kasan_populate_shadow() interface and use it instead of vmemmap_populate(). Besides, this allows us to take advantage of gigantic pages and use them to populate the shadow, which should save us some memory wasted on page tables and reduce TLB pressure.
