+Subject: [PATCH 04/11] fix: btrfs: tracepoints: output proper root owner for
+ trace_find_free_extent() (v5.10)
+
+See upstream commit :
+
+ commit 437490fed3b0c9ae21af8f70e0f338d34560842b
+ Author: Qu Wenruo <wqu@suse.com>
+ Date: Tue Jul 28 09:42:49 2020 +0800
+
+ btrfs: tracepoints: output proper root owner for trace_find_free_extent()
+
+ The current trace event always output result like this:
+
+ find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=4(METADATA)
+ find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=4(METADATA)
+ find_free_extent: root=2(EXTENT_TREE) len=8192 empty_size=0 flags=1(DATA)
+ find_free_extent: root=2(EXTENT_TREE) len=8192 empty_size=0 flags=1(DATA)
+ find_free_extent: root=2(EXTENT_TREE) len=4096 empty_size=0 flags=1(DATA)
+ find_free_extent: root=2(EXTENT_TREE) len=4096 empty_size=0 flags=1(DATA)
+
+ T's saying we're allocating data extent for EXTENT tree, which is not
+ even possible.
+
+ It's because we always use EXTENT tree as the owner for
+ trace_find_free_extent() without using the @root from
+ btrfs_reserve_extent().
+
+ This patch will change the parameter to use proper @root for
+ trace_find_free_extent():
+
+ Now it looks much better:
+
+ find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
+ find_free_extent: root=5(FS_TREE) len=8192 empty_size=0 flags=1(DATA)
+ find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=1(DATA)
+ find_free_extent: root=5(FS_TREE) len=4096 empty_size=0 flags=1(DATA)
+ find_free_extent: root=5(FS_TREE) len=8192 empty_size=0 flags=1(DATA)
+ find_free_extent: root=5(FS_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
+ find_free_extent: root=7(CSUM_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
+ find_free_extent: root=2(EXTENT_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
+ find_free_extent: root=1(ROOT_TREE) len=16384 empty_size=0 flags=36(METADATA|DUP)
