I have 7 patches queued for 3.6 support and will submit for review soon.

[Peng Tao]

Following patches were submitted to gerrit:
http://review.whamcloud.com/3755 kernel: v3.5 defines INVALID_UID
http://review.whamcloud.com/3756 llite: kernel 3.5 renames end_writeback to clear_inode
http://review.whamcloud.com/3757 kernel: 3.5 kernel encode_fh passes in parent inode
http://review.whamcloud.com/4384 kernel: 3.4 kmap_atomic has one argument
http://review.whamcloud.com/4385 kernel: kernel 3.6 changes i_dentry/d_alias to hlist
http://review.whamcloud.com/4386 kernel: 3.6 dentry_open uses struct path as first arg
http://review.whamcloud.com/4387 llite: atomic_open support

They still depend on patches for LU-1337 due to conflicts in lustre_core.m4 file.

To pass sanity in 3.6 kernel, following bugfix patches are also needed (plus patches from LU-1337):
http://review.whamcloud.com/#change,4039
http://review.whamcloud.com/#change,4078
http://review.whamcloud.com/#change,4079
http://review.whamcloud.com/#change,4091
