From 6a9fb468f1152d6254f49fee6ac28c3cfa3367e5 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 20 Jun 2019 15:37:52 -0400 Subject: [PATCH] btrfs: make caching_thread use btrfs_find_next_key extent-tree.c has a find_next_key that just walks up the path to find the next key, but it is used for both the caching stuff and the snapshot delete stuff. The snapshot deletion stuff is special so it can't really use btrfs_find_next_key, but the caching thread stuff can. We just need to fix btrfs_find_next_key to deal with ->skip_locking and then it works exactly the same as the private find_next_key helper.
