Subject: [PATCH] inboxidle: clue users into resolving ENOSPC from inotify
Date: Sat, 26 Dec 2020 05:59:22 +0000	[thread overview]
Message-ID: <20201226055922.19294-1-e@80x24.org> (raw)

It may not be obvious to users a ENOSPC error is from hitting
a (tunable) kernel-imposed limit on inotify watches, and not
some storage device running out of space.  Give them a hint
here to reduce our own support burden.
