Several error paths return\nwithout clearing this flag.\n\nThe transaction restart failure path can leave the flag set on a live\nfilesystem, causing delayed reference processing to be skipped. Clear it\non all free space tree rebuild failure paths. Keep\nBTRFS_FS_FREE_SPACE_TREE_UNTRUSTED set, since a failed rebuild leaves\nthe free space tree untrusted. Callers must fall back to extent-tree\ncaching.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/3565893cc72cdf6b795cf6a33e7ff9605322334d","tags":[]},{"url":"https://git.kernel.org/stable/c/a32bedab8ece9d1f90a1476a5b486a1804dc78ba","tags":[]},{"url":"https://git.kernel.org/stable/c/b1df2997d0cd2be7bef7b4ab64ccfd1019dedc81","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
