The patch titled
Subject: fs/nfsd: change type of max_delegations, nfsd_drc_max_mem and nfsd_drc_mem_used
has been removed from the -mm tree. Its filename was
fs-nfsd-change-type-of-max_delegations-nfsd_drc_max_mem-and-nfsd_drc_mem_used.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Zhang Yanfei <zhangyanfei@xxxxxxxxxxxxxx>
Subject: fs/nfsd: change type of max_delegations, nfsd_drc_max_mem and nfsd_drc_mem_used
The three variables are calculated from nr_free_buffer_pages so
change their types to unsigned long in case of overflow.
