As commented, previously flex_array was used because "we can have large
hash-table without large contiguous kernel memory".
Actually how large can the flow hash table can be? Will this backport
affect currently supported hash table size?
Hi Yifeng,
sorry for the late reply...
The introduction of kvmalloc in the Linux kernel with commit a7c3e901a4
"mm: introduce kv[mz]alloc helpers"
helps explain. kvmalloc_array() will allocate large, contiguous memory
areas.
As noted in this patch by Kent Overstreet we should probably use
rhashtable instead but that would take
additional work and is for future development.
Thanks,

Thanks,
