From: Trond Myklebust Date: Wed, 4 Mar 2015 20:59:05 +0000 (-0500) Subject: NFSv4: Append delegations to the per-client list instead of prepending X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=38942ba204639030b3f3cfe5748a6aff3c9dcc81;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git NFSv4: Append delegations to the per-client list instead of prepending Do so on the assumption that for most use cases, that list will turn into a more or less LRU-ordered list, and so the list traversals in nfs_client_return_marked_delegations() are likely to be shorter before hitting a candidate to return.
