NFSv4/pnfs: Support a list of commit arrays in struct pnfs_ds_commit_info
When we have multiple layout segments with different lists of mirrored data, we need to track the commits on a per layout segment basis. This patch adds a list to support this tracking in struct pnfs_ds_commit_info. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
