Subject: Replace usage of "page" with "bulk" where "page" was actually a "struct
X-Git-Tag: v1_7_100~5586
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=0cc869934a2649250c3ebd5096043868f216f81e

Replace usage of "page" with "bulk" where "page" was actually a "struct
ptlrpc_bulk_page" to avoid (mental) confusion with the kernel "struct page".
