nginx: src/http/ngx_http_file

annotate src/http/ngx_http_file_cache.c @ 4515:8bb695c05870 stable-1.0

Merge of r4498: Fix of rbtree lookup on hash collisions. Previous code incorrectly assumed that nodes with identical keys are linked together. This might not be true after tree rebalance. Patch by Lanshun Zhou.
