Checkpatch.pl doesn't have a check for excluding while (...) {...} blocks from MULTISTATEMENT_MACRO_USE_DO_WHILE error. For example, running checkpatch.pl on the file mm/maccess.c in the kernel generates the following error: ERROR: Macros with complex values should be enclosed in parentheses +#define copy_from_kernel_nofault_loop(dst, src, len, type, err_label) \ + while (len >= sizeof(type)) { \ + __get_kernel_nofault(dst, src, type, err_label); \ + dst += sizeof(type); \ + src += sizeof(type); \ + len -= sizeof(type); \ + } The error is misleading for this case. Enclosing it in parentheses doesn't make any sense. Checkpatch already has an exception list for such common macro types. Added a new exception for while (...) {...} style blocks to the same. In addition, the brace flatten logic was modified by changing the substitution characters from "1" to "1u". This was done to ensure that macros in the form "#define foo(bar) while(bar){bar--;}" were also correctly procecssed.

Checkpatch did not handle cases where the author From: header was split into multiple lines. The author identity could not be resolved and checkpatch generated a false NO_AUTHOR_SIGN_OFF warning. A typical example is commit e33bcbab ("tee: add support for session's client UUID generation"). When checkpatch was run on this commit, it displayed: "WARNING:NO_AUTHOR_SIGN_OFF: Missing Signed-off-by: line by nominal patch author ''" This was due to split header lines not being handled properly and the author himself wrote in commit cd261496 ("checkpatch: warn if missing author Signed-off-by"): "Split From: headers are not fully handled: only the first part is compared." Support split From: headers by correctly parsing the header extension lines. RFC 5322, Section-2.2.3 stated that each extended line must start with a WSP character (a space or htab). The solution was therefore to concatenate the lines which start with a WSP to get the correct long header. Suggested-by:

The uninitialized_var() macro was removed recently via commit 63a0895d ("compiler: Remove uninitialized_var() macro") as it's not a particularly useful warning and its use can "paper over real bugs". Add a checkpatch test to warn on self-assignments as a means to avoid compiler warnings and as a back-door mechanism to reproduce the old uninitialized_var macro behavior.

There are commas used as statement terminations that should typically have used semicolons instead. Only direct assignments or use of a single function or value on a single line are detected by this test. e.g.: foo = bar(), /* typical use is semicolon not comma */ bar = baz(); Add an imperfect test to detect these comma uses. No false positives were found in testing, but many types of false negatives are possible. e.g.: foo = bar() + 1, /* comma use, but not direct assignment */ bar = baz(); Signed-off-by:

Kconfig allows to customize the CONFIG_ prefix via the $CONFIG_ environment variable. Out-of-tree projects may therefore use Kconfig with a different prefix, or they may use a custom configuration tool which does not use the CONFIG_ prefix at all. Such projects may still want to adhere to the Linux kernel coding style and run checkpatch.pl. One example is OP-TEE [1] which does not use Kconfig but does have configuration options prefixed with CFG_. It also mostly follows the kernel coding style and therefore being able to use checkpatch is quite valuable. To make this possible, add the --kconfig-prefix command line option.

Whether crc32_be needs a lookup table is chosen based on CRC_LE_BITS. Obviously, the _be function should be governed by the _BE_ define. This probably never pops up as it's hard to come up with a configuration where CRC_BE_BITS isn't the same as CRC_LE_BITS and as nobody is using bitwise CRC anyway.
