From: Nikolay Borisov Date: Tue, 15 Oct 2019 15:42:23 +0000 (+0300) Subject: btrfs: Rename find_oldest_super_backup to init_backup_root_slot X-Git-Tag: v5.10.7~3450^2~58 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4ac039ad75df3f5f5f5b2b7439f094ad5bd9dbbe;p=platform%2Fkernel%2Flinux-rpi.git btrfs: Rename find_oldest_super_backup to init_backup_root_slot The old name name was an awful misnomer because it didn't really find the oldest super backup per-se but rather its slot. For example if we have: slot0: gen - 2 slot1: gen - 1 slot2: gen slot3: empty init_backup_root_slot will return slot3 and not slot0. The new name is more appropriate since the function doesn't care whether there is a valid backup in the returned slot or not.
