Subject: fs: Fix file mode for O_TMPFILE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e305f48bc453da773a3601135a2cce40b8e62856;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

fs: Fix file mode for O_TMPFILE

O_TMPFILE, like O_CREAT, should respect the requested mode and should
create regular files.

This fixes two bugs: O_TMPFILE required privilege (because the mode
ended up as 000) and it produced bogus inodes with no type.
