Subject: hugetlb: No coalescing of adjacent mappings in /proc/pid/maps
Date: Wed, 6 Nov 2002 07:26:44 +0100 [thread overview]
Message-ID: <051a01c2855d$7aec8990$760010ac@edumazet> (raw)

Hello William
I noticed a small problem if a process allocates hugetlb memory using
sys_alloc_hugepages(0, 0, 4*1024*1024, PROT_READ|PROT_WRITE, 0) ;
If this process uses a lot of hugetlb pages, its /proc/pid/maps contains one
entry for each mapping.
Could it be possible to coalesce all consecutive mappings onto only one ? As
standard mmap() calls do ?
