pid: add helpers to operate on a struct pid array

2026-09-09T12:39:40+00:00

We're about to extend af_unix sockets and coredump code with the ability to hand out thread-specific pidfds. Add a few simple helpers that allow to operate on multiple struct pids up to PIDTYPE_MAX with automatic bounds checking.

docs: python: abi_regex: convert adjacent index placeholders

2026-08-11T16:36:28+00:00

While validating recent CXL ABI documentation updates with get_abi.py, every decoderX.Y entry was reported as undocumented. The placeholder conversion mishandles adjacent index placeholders, producing patterns that cannot match the corresponding sysfs paths. As a result, valid ABI entries are reported as undocumented. Handle adjacent placeholders independently so generated patterns match the documented paths. This fixes decoderX.Y entries in the CXL ABI and other ABI documentation that uses the same naming convention. Signed-off-by: Alison Schofield Signed-off-by: Jonathan Corbet Message-ID:

docs: python: abi_regex: catch the right exception for a bad regex

2026-08-11T16:36:28+00:00

While validating recent CXL ABI documentation updates with get_abi.py, the 'undefined' mode was found to abort instead of reporting undocumented ABI entries. Older Python releases raise re.error, while newer releases expose re.PatternError. Catching the compatible re.error exception handles both cases. Use re.error so the scan continues and reports the remaining results.

docs: kdoc_parser: drop extraneous blank line in warning message

2026-08-03T18:07:17+00:00

Drop an extra newline (blank line) on warning messages for (2 places): expecting prototype for typedef. Prototype was for typedef {symbol} instead and expecting prototype for {struct|union}. Prototype was for struct|union {symbol} instead This makes these messages consistent with the similar enum warning, which has no extra blank line.

scripts/kernel-doc: Suggest possible names for excess descriptions

2026-07-22T16:10:44+00:00

Recent check_sections() change added a warning if a documentation tag member name does not match the detected struct/union member names. Since the checker knows all possible names, we can suggest known names, so that it's more obvious how to deal with the warning.
