linux.git/fs/fcntl.c, branch v3.11 Linux kernel source tree vfs: add missing check for __O_TMPFILE in fcntl_init() 2013-08-05T14:25:32+00:00 Zheng Liu gnehzuil.liu@gmail.com 2013-07-25T00:13:19+00:00 3d62c45b38e534262d443b5820fb06a0e6d0d42f As comment in include/uapi/asm-generic/fcntl.h described, when introducing new O_* bits, we need to check its uniqueness in fcntl_init(). But __O_TMPFILE bit is missing. So fix it. Signed-off-by: Zheng Liu <wenqing.lz@taobao.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
