commit ebae102897e760e9e6bc625f701dd666b2163bd1 upstream.
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.
