Requesting a v3 please.
Please add the __glibc_reserved* members to the structures to preserve
maximum compatibility with the kernel structure.
See review of patch 14/25 for more general details.
I am almost OK with this change as-is because in general everyone
should be using statx at this point with the ability to extend and
provide more information.
However because the kernel contains:
24 struct stat {
25 unsigned long st_dev; /* Device. */
26 unsigned long st_ino; /* File serial number. */
27 unsigned int st_mode; /* File mode. */
28 unsigned int st_nlink; /* Link count. */
29 unsigned int st_uid; /* User ID of the file's owner. */
30 unsigned int st_gid; /* Group ID of the file's group. */
31 unsigned long st_rdev; /* Device number, if device. */
32 unsigned long __pad1;
33 long st_size; /* Size of file, in bytes. */
34 int st_blksize; /* Optimal block size for I/O. */
35 int __pad2;
36 long st_blocks; /* Number 512-byte blocks allocated. */
37 long st_atime; /* Time of last access. */
38 unsigned long st_atime_nsec;
39 long st_mtime; /* Time of last modification. */
40 unsigned long st_mtime_nsec;
41 long st_ctime; /* Time of last status change. */
42 unsigned long st_ctime_nsec;
43 unsigned int __unused4;
44 unsigned int __unused5;
45 };
With __unused4 and __unused5. I think we should match this ABI as closely as we can
to avoid future compatibility issues with legacy APIs.
