Subject: dax: make 'wait_table' global variable static
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ce95ab0fa669698805ff8841a756733a7702b5c9;p=linux-beck.git

dax: make 'wait_table' global variable static

The global 'wait_table' variable is only used within fs/dax.c, and
generates the following sparse warning:

fs/dax.c:39:19: warning: symbol 'wait_table' was not declared. Should it be static?

Make it static so it has scope local to fs/dax.c, and to make sparse happy.
