There is no race to win and no memory-layout precondition outside the attacker's control.\nPR:L - The only access control on the path is inode_owner_or_capable(), so any unprivileged local user who owns a file on the GFS2 mount can flip the flag; fileattr_set_prepare() restricts only APPEND/IMMUTABLE and project IDs, not FS_JOURNAL_DATA_FL.
