[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v9 03/16] x86: rename 'cbm_type' to 'psr_type' to make it general
This patch renames 'cbm_type' to 'psr_type' to generalize it.
Then, we can reuse this for all psr allocation features.

v5:
- correct character of reviewer's name.
(suggested by Jan Beulich)
v4:
- fix words in commit message.
(suggested by Roger Pau Monné)
v3:
- replace 'psr_val_type' to 'psr_type' and remove '_VAL' from the enum
items.
(suggested by Roger Pau Monné)
v2:
- replace 'PSR_VAL_TYPE_{L3, L2}' to 'PSR_VAL_TYPE_{L3, L2}_CBM'.
(suggested by Chao Peng)
