[lttng-dev] [PATCH 00/12] rculfhash memory managements

[laijs@cn.fujitsu.com (Lai Jiangshan)]

3fd3f554f6eb18ae5ec526b82025a53a554f775d are wrong,

1) dynamic len tbl_chunk must at the end of cds_lfht, (so I put all the mm field at the end of cds_lfht).

2) lists of hot access fields:
size
tbl_order/chunk/mmap
bucket_at
flags (testing for counting)
split_count
min_alloc_buckets_order (bucket_at() for chunk mm)
min_nr_alloc_buckets (buket_at() for order mm and chunk mm)

They are many, so I group them by functional, not accessing ratio.
