Subject: [PATCH] xfsprogs: guard fsxattr definition for newer kernels
Date: Tue, 9 Feb 2016 11:40:57 -0600	[thread overview]
Message-ID: <56BA24A9.4090403@redhat.com> (raw)

After 334e580,
fs: XFS_IOC_FS[SG]SETXATTR to FS_IOC_FS[SG]ETXATTR promotion

the file include/linux/fs.h now defines struct fsxattr.

It defines FS_IOC_FSGETXATTR as well, so use that to wrap
our local definition, and skip it if the kernel is providing
it so that we don't get multiple definitions.

Signed-off-by: Eric Sandeen <sandeen@redhat.com>
---

Should the kernel also #define HAVE_FSXATTR to help existing
xfsprogs-devel installations?

(And what if headers are included in the other order?  Should
we try to guard on the kernel side or no?)
