[Cluster-devel] [GFS2 PATCH 2/4] GFS2: Make block reservations more persistent

[Bob Peterson]

Before this patch, whenever a struct file (opened to allow writes) was
closed, the multi-block reservation structure associated with the inode
was deleted. That's a problem, especially when there are multiple writers.
Applications that do open-write-close will suffer from greater levels
of fragmentation and need to re-do work to perform write operations.
This patch removes the reservation delete from the file close code so
that they're more persistent until the inode is deleted.
