RHEL6.2 pathcless client needs to be supported on 1.8.x. Intel and AMD CPU based server requires rhel6.2's kernel to support full functions and performance. The master branch supports for this distribution, so at least we need backport the following patches from master branch, and one code change for the patchless client.
LU-766 Incorrect HAVE_STATFS_DENTRY_PARAM result
LU-778 RHEL 6.2: rdma_create_id() takes four arguments
LU-1050 configure broken on centos6.2 with OFED-1.5.4
On rhel6.2's kenrel, an function name roundup() in include/linux/kernel.h was changed to round_up() which is duplicated what the lustre used in lustre/mdc/mdc_locks.c.
So, we may need to change this function name like lu_round_up(). This is discussed on wc-discuss.

Lustre 1.8.x known issues tracker
While testing against Lustre b18 branch, we would hit known bugs which were already reported in Lustre Bugzilla https://bugzilla.lustre.org/. In order to move away from relying on Bugzilla, we would create a JIRA
