Subject: sunrpc: increase MAX_HASHTABLE_BITS to 14
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=db5fe26541b6b48460104a0d949a27cdc7786957;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

sunrpc: increase MAX_HASHTABLE_BITS to 14

The maximum size of the authcache is now set to 1024 (10 bits),
but on our server we need at least 4096 (12 bits). Increase
MAX_HASHTABLE_BITS to 14. This is a maximum of 16384 entries,
each containing a pointer (8 bytes on x86_64). This is
exactly the limit of kmalloc() (128K).
