Describe the fallthrough pseudo-keyword. Convert the coding-style.rst example to the keyword style. Add description and links to deprecated.rst. Miguel Ojeda comments on the eventual [[fallthrough]] syntax: "Note that C17/C18 does not have [[fallthrough]]. C++17 introduced it, as it is mentioned above. I would keep the __attribute__((fallthrough)) -> [[fallthrough]] change you did, though, since that is indeed the standard syntax (given the paragraph references C++17). I was told by Aaron Ballman (who is proposing them for C) that it is more or less likely that it becomes standardized in C2x. However, it is still not added to the draft (other attributes are already, though). See N2268 and N2269: http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2268.pdf (fallthrough) http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2269.pdf (attributes in general)" Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Nick Desaulniers <ndesaulniers@google.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Reserve the pseudo keyword 'fallthrough' for the ability to convert the various case block /* fallthrough */ style comments to appear to be an actual reserved word with the same gcc case block missing fallthrough warning capability. All switch/case blocks now should end in one of: break; fallthrough; goto <label>; return [expression]; continue; In C mode, GCC supports the __fallthrough__ attribute since 7.1, the same time the warning and the comment parsing were introduced. fallthrough devolves to an empty "do {} while (0)" if the compiler version (any version less than gcc 7) does not support the attribute.

Depending on inlining decisions by the compiler, __get/put_user_fn might become out of line. Then the compiler is no longer able to tell that size can only be 1,2,4 or 8 due to the check in __get/put_user resulting in false positives like ./arch/s390/include/asm/uaccess.h: In function ‘__put_user_fn’: ./arch/s390/include/asm/uaccess.h:113:9: warning: ‘rc’ may be used uninitialized in this function [-Wmaybe-uninitialized] 113 | return rc; | ^~ ./arch/s390/include/asm/uaccess.h: In function ‘__get_user_fn’: ./arch/s390/include/asm/uaccess.h:143:9: warning: ‘rc’ may be used uninitialized in this function [-Wmaybe-uninitialized] 143 | return rc; | ^~ These functions are supposed to be always inlined.

Commit 4b708b7b ("firmware: google: check if size is valid when decoding VPD data") adds length checks, but the new vpd_decode_entry() function botched the logic -- it adds the key length twice, instead of adding the key and value lengths separately. On my local system, this means vpd.c's vpd_section_create_attribs() hits an error case after the first attribute it parses, since it's no longer looking at the correct offset. With this patch, I'm back to seeing all the correct attributes in /sys/firmware/vpd/...

We have two ways a request can be deferred: 1) It's a regular request that depends on another one 2) It's a timeout that tracks completions We have a shared helper to determine whether to defer, and that attempts to make the right decision based on the request. But we only have some of this information in the caller. Un-share the two timeout/defer helpers so the caller can use the right one.
