38 * Some old glibc headers don't define BLKGETSIZE64

41 #if !defined(BLKGETSIZE64)
42 #define BLKGETSIZE64 _IOR(0x12, 114, size_t)
46 * Some old glibc headers don't correctly define MS_DIRSYNC and
47 * instead use the enum name S_WRITE. When using these older
48 * headers define MS_DIRSYNC to be S_WRITE.
50 #if !defined(MS_DIRSYNC)
51 #define MS_DIRSYNC S_WRITE
55 * Some old glibc headers don't correctly define MS_POSIXACL and
56 * instead leave it undefined. When using these older headers define
57 * MS_POSIXACL to the reserved value of (1<<16).

69 * Older glibc <sys/mount.h> headers did not define all the available
70 * umount2(2) flags. Both MNT_FORCE and MNT_DETACH are supported in the
71 * kernel back to 2.4.11 so we define them correctly if they are missing.

86 * Overlay mount is default in Linux, but for solaris/zfs
87 * compatibility, MS_OVERLAY is defined to explicitly have the user
88 * provide a flag (-O) to mount over a non empty directory.
