Description

Recent commit d7ac66d2fddc3b2a6fb91b6421f9a15b80c8d10a, LU-2748 osd: allocate buffers on demand, has broken the lustre server build on sles11sp2. errors:

The new added call to ldiskfs_map_inode_page() takes 5 args in the 3.0 kernel in sles11sp2, not the 4 args used in the 2.6 kernel. Needs some autoconf mods and #ifdefs to adapt to different kernel versions.

I suspect the build on the 3.7 kernel in FC18 may be broken too.

This isn't a critical bug right now because we don't routinely enable server builds on sles11sp2 yet.
