Subject: [PATCH 13/17] smb: client: reduce stack usage in cifs_demultiplex_thread()
Date: Thu, 17 Aug 2023 12:34:11 -0300	[thread overview]
Message-ID: <20230817153416.28083-14-pc@manguebit.com> (raw)
In-Reply-To: <20230817153416.28083-1-pc@manguebit.com>

Clang warns about exceeded stack frame size

  fs/smb/client/connect.c:1109:1: warning: stack frame size (1048)
  exceeds limit (1024) in 'cifs_demultiplex_thread'
  [-Wframe-larger-than]

It turns out that clean_demultiplex_info() got inlined into
cifs_demultiplex_thread(), so mark it as noinline_for_stack to save
some stack space.
