Subject: [PATCH v2 md-6.17] md: rename recovery_cp to resync_offset
From: Li Nan <linan122@...wei.com>
'recovery_cp' was used to represent the progress of sync, but its name
contains recovery, which can cause confusion. Replaces 'recovery_cp'
with 'resync_offset' for clarity.
Signed-off-by: Li Nan <linan122@...wei.com>
