"xxx``at``" makes the `` appear verbatim in the HTML output. I've opted for changing this into ``*at()`` to harmonise this with the use of * seen later in the same document (and add the parentheses to clarify that this is a system/function call). ``path_``* also makes `` appear in the HTML output, but we can fix it by moving the * into the ``. Also add the parantheses here. Signed-off-by: Vegard Nossum <redacted> --- Documentation/filesystems/path-lookup.rst | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-)
