Subject: Don't fail allocations for the slot table when mounting an NFS filesystem
|
|
Patch-mainline: no
|
|
References: bnc#519820
|
|
|
|
When the *_slot_table_entries exceeds 111, the slot_table_size
|
|
exceeds 32K and an order-4 allocation is forced. This does not
|
|
retry nearly as much as order-3 so failure is more likely.
|
|
But mount and autofs in particular doesn't cope well with failure.
|
|
So force __GFP_REPEAT - the assumption is that people will only
|
|
set the slot_table_size sysctl large on a machine with plenty
|
|
of memory, so this should not block indefinitely.
