From 91d34a22049c68298ea825256f4674bca0790957 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Tue, 4 Jun 2019 15:18:43 +0200 Subject: [PATCH] UPSTREAM: signal: improve comments Improve the comments for pidfd_send_signal(). First, the comment still referred to a file descriptor for a process as a "task file descriptor" which stems from way back at the beGinning of the discussion. Replace this with "pidfd" for consistency. Second, the wording for the explanation of the arguments to the syscall was a bit inconsistent, e.g. some used the past tense some used present tense. Make the wording more consistent.
