vfs: add missing check for __O_TMPFILE in fcntl_init()

2013-08-05T14:25:32Z

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 Signed-off-by: Al Viro

Fix F_DUPFD_CLOEXEC breakage

2012-10-09T06:52:31Z

Fix a braino in F_DUPFD_CLOEXEC; f_dupfd() expects flags for alloc_fd(), get_unused_fd() etc and there clone-on-exec if O_CLOEXEC, not FD_CLOEXEC. Reported-by: Richard W.M. Jones Signed-off-by: Al Viro Signed-off-by: Linus Torvalds

take rlimit check to callers of expand_files()

2012-09-27T01:08:53Z

... except for one in android, where the check is different and already done in caller. No need to recalculate rlimit many times in alloc_fd() either. Signed-off-by: Al Viro

c/r: fcntl: add F_GETOWNER_UIDS option

2012-07-31T00:25:21Z

When we restore file descriptors we would like them to look exactly as they were at dumping time. With help of fcntl it's almost possible, the missing snippet is file owners UIDs. To be able to read their values the F_GETOWNER_UIDS is introduced. This option is valid iif CONFIG_CHECKPOINT_RESTORE is turned on, otherwise returning -EINVAL.
