Subject: [for-next][PATCH 41/46] tracing: Remove filter allocator helper
Date: Tue, 20 Mar 2018 22:21:33 -0400 [thread overview]
Message-ID: <20180321022131.190058562@goodmis.org> (raw)
In-Reply-To: 20180321022052.030055576@goodmis.org
[-- Attachment #1: 0041-tracing-Remove-filter-allocator-helper.patch --]
[-- Type: text/plain, Size: 1601 bytes --]
From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>
The __alloc_filter() function does nothing more that allocate the filter.
There's no reason to have it as a helper function.
Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
