Patch changelog: v2: * Add include <linux/types.h> to openat2.h. [Florian Weimer] * Move OPEN_HOW_SIZE_* constants out of UAPI. [Florian Weimer] * Switch from __aligned_u64 to __u64 since it isn't necessary. [David Laight] v1: https://lore.kernel.org/lkml/20191219105533.12508-1-cyphar@cyphar.com/
While openat2(2) is still not yet in Linus's tree, we can take this opportunity to iron out some small warts that weren't noticed earlier:
* A fix was suggested by Florian Weimer, to separate the openat2 definitions so glibc can use the header directly. I've put the maintainership under VFS but let me know if you'd prefer it belong ot the fcntl folks.
* Having heterogenous field sizes in an extensible struct results in "padding hole" problems when adding new fields (in addition the correct error to use for non-zero padding isn't entirely clear ). The simplest solution is to just copy clone(3)'s model -- always use u64s. It will waste a little more space in the struct, but it removes a possible future headache.
