Subject: Silence 'old_umask' uninit variable warning
X-Git-Url: https://git.camperquake.de/gitweb.cgi?p=zfs.git;a=commitdiff_plain;h=a4914d38a794915c774670307d6f61480eba2046

Silence 'old_umask' uninit variable warning

Recent changes have caused older versions of gcc to mistakenly
flag 'old_umask' in vn_open() as an unitialized variable.  To
silence the warning initialize it.

  kernel.c: In function 'vn_open':
  kernel.c:525:6: error: 'old_umask' may be used uninitialized
  in this function
