    gfs2: clear buf_in_tr when ending a transaction in sweep_bh_for_rgrps · f0b444b3
    Bob Peterson authored
    In function sweep_bh_for_rgrps, which is a helper for punch_hole,
    it uses variable buf_in_tr to keep track of when it needs to commit
    pending block frees on a partial delete that overflows the
    transaction created for the delete. The problem is that the
    variable was initialized at the start of function sweep_bh_for_rgrps
    but it was never cleared, even when starting a new transaction.
    
    This patch reinitializes the variable when the transaction is
    ended, so the next transaction starts out with it cleared.
    
    Fixes: d552a2b9 ("GFS2: Non-recursive delete")
