mm/page_alloc.c: remove duplicate call to trace_mm_page_free_direct
trace_mm_page_free_direct() is called in function __free_pages(). But it is called again in free_hot_page() if order == 0 and produce duplicate records in trace file for mm_page_free_direct event. As below: K-PID CPU# TIMESTAMP FUNCTION gnome-terminal-1567 [000] 4415.246466: mm_page_free_direct: page=ffffea0003db9f40 pfn=1155800 order=0 gnome-terminal-1567 [000] 4415.246468: mm_page_free_direct: page=ffffea0003db9f40 pfn=1155800 order=0 gnome-terminal-1567 [000] 4415.246506: mm_page_alloc: page=ffffea0003db9f40 pfn=1155800 order=0 migratetype=0 gfp_flags=GFP_KERNEL gnome-terminal-1567 [000] 4415.255557: mm_page_free_direct: page=ffffea0003db9f40 pfn=1155800 order=0 gnome-terminal-1567 [000] 4415.255557: mm_page_free_direct: page=ffffea0003db9f40 pfn=1155800 order=0 This patch removes the first call and adds a call to trace_mm_page_free_direct() in __free_pages_ok().
