[PATCH v22 08/27] xfsprogs: Hoist node transaction handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Source kernel commit: cb9e8e1fb89d84c77c8035b2391359f9cbf209e6

This patch basically hoists the node transaction handling around the
leaf code we just hoisted.  This will helps setup this area for the
state machine since the goto is easily replaced with a state since it
ends with a transaction roll.
