2025-03-18xfs: remove xfs_buf_free_mapsChristoph Hellwig
xfs_buf_free_maps only has a single caller, so open code it there. Stop zeroing the b_maps pointer as the buffer is freed in the next line. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Carlos Maiolino <cmaiolino@redhat.com> Signed-off-by: Carlos Maiolino <cem@kernel.org>

xfs_buf_get_maps has a single caller, and can just be open coded there. When doing that, stop handling the allocation failure as we always pass __GFP_NOFAIL to the slab allocator, and use the proper kcalloc helper for array allocations.

2025-03-18xfs: call xfs_buf_alloc_backing_mem from _xfs_buf_allocChristoph Hellwig
We never allocate a buffer without backing memory. Simplify the call chain by calling xfs_buf_alloc_backing_mem from _xfs_buf_alloc. To avoid a forward declaration, move _xfs_buf_alloc down a bit in the file. Also drop the pointless _-prefix from _xfs_buf_alloc.

2025-03-18ALSA: usb-audio: separate DJM-A9 cap lvl optionsOlivia Mackintosh
Mixer quicks for the Pioneer DJM-A9 mixer was added in 5289d00 with additional capture level values added to the common DJM array of values. This breaks the existing DJM mixers however as alsa-utils relies on enumeration of the actual mixer options based on the value array which results in error when storing state.

2025-03-18riscv: ftrace: Add parentheses in macro definitions of make_call_t0 and ↵Juhan Jin
make_call_ra This patch adds parentheses to parameters caller and callee of macros make_call_t0 and make_call_ra. Every existing invocation of these two macros uses a single variable for each argument, so the absence of the parentheses seems okay. However, future invocations might use more complex expressions as arguments. For example, a future invocation might look like this: make_call_t0(a - b, c, call). Without parentheses in the macro definition, the macro invocation expands to: ... unsigned int offset = (unsigned long) c - (unsigned long) a - b; ... which is clearly wrong. The use of parentheses ensures arguments are correctly evaluated and potentially saves future users of make_call_t0 and make_call_ra debugging trouble.

2025-03-18wifi: iwlwifi: dvm: Avoid -Wflex-array-member-not-at-end warningsGustavo A. R. Silva
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. So, in order to avoid ending up with a flexible-array member in the middle of multiple other structs, we use the `__struct_group()` helper to create a new tagged `struct iwl_tx_cmd_hdr`. This structure groups together all the members of the flexible `struct iwl_tx_cmd` except the flexible array. As a result, the array is effectively separated from the rest of the members without modifying the memory layout of the flexible structure. We then change the type of the middle struct members currently causing trouble from `struct iwl_tx_cmd` to `struct iwl_tx_cmd_hdr`. We also want to ensure that when new members need to be added to the flexible structure, they are always included within the newly created tagged struct. For this, we use `static_assert()`. This ensures that the memory layout for both the flexible structure and the new tagged struct is the same after any changes. This approach avoids having to implement `struct iwl_tx_cmd_hdr` as a completely separate structure, thus preventing having to maintain two independent but basically identical structures, closing the door to potential bugs in the future. So, with these changes, fix the following warnings: drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2315:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/dvm/commands.h:2426:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

2025-03-18inet: frags: save a pair of atomic operations in reassemblyEric Dumazet
As mentioned in commit 648700f76b03 ("inet: frags: use rhashtables for reassembly units"): A followup patch will even remove the refcount hold/release left from prior implementation and save a couple of atomic operations. This patch implements this idea, seven years later.

2025-03-18inet: frags: change inet_frag_kill() to defer refcount updatesEric Dumazet
In the following patch, we no longer assume inet_frag_kill() callers own a reference. Consuming two refcounts from inet_frag_kill() would lead in UAF. Propagate the pointer to the refs that will be consumed later by the final inet_frag_putn() call.

2025-03-18xfs: don't wake zone space waiters without m_zone_infoDarrick J. Wong
xfs_zoned_wake_all checks SB_ACTIVE to make sure it does the right thing when a shutdown happens during unmount, but it fails to account for the log recovery special case that sets SB_ACTIVE temporarily. Add a NULL check to cover both cases. Signed-off-by: Darrick J.

2025-03-18xfs: don't increment m_generation for all errors in xfs_growfs_dataChristoph Hellwig
xfs_growfs_data needs to increment m_generation as soon as the primary superblock has been updated. As the update of the secondary superblocks was part of xfs_growfs_data_private that mean the incremented had to be done unconditionally once that was called. Later, commit 83a7f86e39ff ("xfs: separate secondary sb update in growfs") split the secondary superblock update into a separate helper, so now the increment on error can be limited to failed calls to xfs_update_secondary_sbs.
