Subject: vfs: atomic_open(): fix create mode usage
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=62b259d8b3ea9d4a73108fc599e40c863ec25ae6;p=openwrt%2Fstaging%2Fblogic.git

vfs: atomic_open(): fix create mode usage

Don't mask S_ISREG off the create mode before passing to ->atomic_open().  Other
methods (->create, ->mknod) also get the complete file mode and filesystems
expect it.
