[PATCH v2 35/46] staging/lustre/llite: Rename struct vvp_thread_info to ll_thread_info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: John Hammond <john.hammond@xxxxxxxxx>

struct vvp_thread_info is used in the non-VVP parts of llite so rename
it struct ll_thread_info. Rename supporting functions accordingly.
