Hi folks,
There are two parts to this patchset. The first is ensuring that
xfsprogs builds correctly with the new kernel header provided
definitions of XFS_IOC_FS[SG]SETXATTR and it's flags. I modified
my original approach to this to hide the definitions of the FS*
ioctl and flags in the platofrm headers if the system didn't provide
them.
While this does result in some duplication, it solves the problem of
needing different definitions for FS_IOC_FS[SG]ETXATTR on different
platforms - they are different ioctl names on IRIX, so we can't just
define it once in xfs_fs.h. The detection can also then be different
- we only include the definitions on linux if we don't have the
system version, and on the other platforms it retains the
HAVE_FSXATTR guards.
The second and third patches are adding support for the FS_XFLAG_DAX
and enabling xfs_io to set, get and clear the flag. Actual support
of the on disk flag in libxfs will come in a later patchset that
adds support into db and repair, too. This is the patchset I used to
test the kernel side flag support.
Comments and testing welcome.
Cheers,
Dave.

This enables (initially) ext4 to use the ioctl to set project IDs on inodes. This means we now need to handle this change in userspace as the uapi/linux/fs.h file may not contain the definitions (i.e. new xfsprogs/ old linux uapi files) xfsprogs needs to build. Hence we need to massage the definition in xfs_fs.h to take the values from the system header if it exists, otherwise keep the old definitions for compatibility and platforms other than linux. To this extent, we add the FS* definitions to the platform headers so the FS* versions are available on all platforms, and add trivial defines to xfs_fs.h to present the XFS* versions for backwards compatibility with existing code. New code should always use the FS* versions, and as such we also convert all the users of XFS* in xfsprogs to use the FS* definitions.

This patch introduces a new inode flag to enable DAX in the v3 inode di_flags2 field. It adds support for setting and clearing flags in the di_flags2 field via the XFS_IOC_FSSETXATTR ioctl, and sets the S_DAX inode flag appropriately when it is seen. When this flag is set on a directory, it acts as an "inherit flag". That is, inodes created in the directory will automatically inherit the on-disk inode DAX flag, enabling administrators to set up directory heirarchies that automatically use DAX. Setting this flag on an empty root directory will make the entire filesystem use DAX by default.
