[PATCH 0/14] pnfs_submit file layout client device management

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

 



Apply against 2.6.34-rc3 pnfs branch. For pNFS client submission. Only touches
the file layout driver.

This set of patches implements several design changes enmerated at
http://wiki.linux-nfs.org/wiki/index.php/Porposed_Device_ Manangement_Design.

- Only call GETDEVICEINFO from one place
- Only cache the first data server in the multipath_list4 array.
- Wait to connect to data server when needed for I/O
- Move data server cache to stand alone cache

Also some cleanup, and function interfaces are changed in 
preparation for the soon to come generic deviceid cache.
