ENOSYS means that a nonexistent system call was called. We have a
bad habit of using it for things like invalid operations on
otherwise valid syscalls. We should avoid this in new code.
Pervasive incorrect usage of ENOSYS came up at the kernel summit ABI
review discussion. Let's see if checkpatch can help.
I'll submit a separate patch for include/uapi/asm-generic/errno.h.

const objects shouldn't be __read_mostly. They are read-only.
Marking these objects as __read_mostly causes section conflicts with LTO
linking.

Code such as:
x = timercmp(&now, &end, <);
Will currently trigger a checkpatch error. e.g.
ERROR: spaces required around that '<'
This is because the "Ignore operators passed as parameters" check looks
only for a comma following the operator. Improve the check by also
looking for a close parenthesis.

Commit messages lines are sometimes overly long.
Suggest line wrapping at 75 columns so the default git commit log
indentation of 4 plus the commit message text still fits on an 80 column

Checkpatch flags CamelCase identifiers in strict mode, but it has a
feature to ignore parts with only two characters to allow for SI units
like mV or uA. Unfortunately, not all SI units fit in two characters, and
not all are lower case followed by upper case.
This patch adds hardcoded detection for frequency and 1024-based size
units (Hz/KHz/MHz/GHz/THz and KiB/MiB/GiB/TiB), since allowing any three
character combinations might be too lenient. The list can later be
expanded as needed.

Macros with flow control statements (goto and return) are not very nice to
read as any flow movement is unexpected.
Try to highlight them and emit a warning on their definition.
Avoid warning on macros that use argument concatenation as those macros
commonly create another function where the concatenation is used in the
function name definition like:
#define FOO_FUNC(name, rtn_type) \
rtn_type func##name(arg1, ...) \
{ \
rtn_type rtn; \
[code...] \
return rtn; \
