Subject: [PATCH v3 03/13] fanotify: rename struct fanotify_{,perm_}event_info
Date: Sun, 25 Nov 2018 15:43:42 +0200	[thread overview]
Message-ID: <20181125134352.21499-4-amir73il@gmail.com> (raw)
In-Reply-To: <20181125134352.21499-1-amir73il@gmail.com>

struct fanotify_event_info "inherits" from struct fsnotify_event and
therefore a more appropriate (and short) name for it is fanotify_event.
Same for struct fanotify_perm_event_info, which now "inherits" from
struct fanotify_event.

We plan to reuse the name struct fanotify_event_info for user visible
event info record format.
