From: Andy Shevchenko Date: Thu, 13 Nov 2025 08:31:31 +0000 (+0100) Subject: nfsd: Mark variable __maybe_unused to avoid W=1 build break X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ebae102897e760e9e6bc625f701dd666b2163bd1;p=thirdparty%2Flinux.git nfsd: Mark variable __maybe_unused to avoid W=1 build break Clang is not happy about set but (in some cases) unused variable: fs/nfsd/export.c:1027:17: error: variable 'inode' set but not used [-Werror,-Wunused-but-set-variable] since it's used as a parameter to dprintk() which might be configured a no-op. To avoid uglifying code with the specific ifdeffery just mark the variable __maybe_unused. The commit [1], which introduced this behaviour, is quite old and hence the Fixes tag points to the first of the Git era.
