However, this can obviouly race with concurrent tree\nmodifications.\n\nInstead, we now look into the extent while we\u0027re holding the lock during\nfind_all_leafs and store this information together with the leaf list.\n\nSigned-off-by: Jan Schmidt \u003clist.btrfs@jan-o-sch.net\u003e\n"

This\nassumes we\u0027re searching live roots, which requires a transaction context.\nWhile scrubbing, however, we must not join a transaction because this could\ndeadlock with the commit path. Additionally, what scrub really wants to do\nis resolving a logical address in the commit root it\u0027s currently checking.\n\nThis patch adds support for logical to path resolving on commit roots and\nmakes scrub use that.\n\nSigned-off-by: Jan Schmidt \u003clist.btrfs@jan-o-sch.net\u003e\n"
