From: Jonathan Corbet Date: Sat, 21 Jun 2025 20:35:04 +0000 (-0600) Subject: docs: kdoc: Make body_with_blank_line parsing more flexible X-Git-Tag: io_uring-6.17-20250815~111^2~77 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=823d6f956605cb2f009f75de138622fcd7e03817;p=linux-block.git docs: kdoc: Make body_with_blank_line parsing more flexible The regex in the BODY_WITH_BLANK_LINE case was looking for lines starting with " * ", where exactly one space was allowed before the following text. There are many kerneldoc comments where the authors have put multiple spaces instead, leading to mis-formatting of the documentation. Specifically, in this case, the description portion is associated with the last of the parameters. Allow multiple spaces in this context. See, for example, synchronize_hardirq() and how its documentation is formatted before and after the change.
