Nils Goroll authoredI got this wrong in 69695c23 for the case that the segment spans two pages. Ref: #2541 mmaps from b25.vtc varnishstat: before this change: 6598 open("/tmp/vtc.6492.2b3b5875/v1//_.vsm_child/_.VSC_cluster.322833fd50de0860", O_RDONLY) = 21 6598 mmap(NULL, 4096, PROT_READ, MAP_SHARED, 21, 0) = 0x7fb92529e000 ... 6598 open("/tmp/vtc.6492.2b3b5875/v1//_.vsm_child/_.VSC_cluster.322833fd50de0860", O_RDONLY) = 21 6598 mmap(NULL, 8192, PROT_READ, MAP_SHARED, 21, 0) = 0x7fb925271000 ... 6598 open("/tmp/vtc.6492.2b3b5875/v1//_.vsm_child/_.VSC_cluster.322833fd50de0860", O_RDONLY) = 21 6598 mmap(NULL, 12288, PROT_READ, MAP_SHARED, 21, 0x1000) = 0x7fb925222000 ... 6598 open("/tmp/vtc.6492.2b3b5875/v1//_.vsm_child/_.VSC_cluster.322833fd50de0860", O_RDONLY) = 21 6598 mmap(NULL, 12288, PROT_READ, MAP_SHARED, 21, 0x2000) = 0x7fb92521f000 after this change: 7749 open("/tmp/vtc.7648.2c3869d9/v1//_.vsm_child/_.VSC_cluster.09720dc34dd3559c", O_RDONLY) = 21 7749 mmap(NULL, 4096, PROT_READ, MAP_SHARED, 21, 0) = 0x7f0938a28000 ... 7749 open("/tmp/vtc.7648.2c3869d9/v1//_.vsm_child/_.VSC_cluster.09720dc34dd3559c", O_RDONLY) = 21 7749 mmap(NULL, 4096, PROT_READ, MAP_SHARED, 21, 0x1000) = 0x7f09389f9000 ... 7749 open("/tmp/vtc.7648.2c3869d9/v1//_.vsm_child/_.VSC_cluster.09720dc34dd3559c", O_RDONLY) = 21 7749 mmap(NULL, 8192, PROT_READ, MAP_SHARED, 21, 0x1000) = 0x7f09389d2000 ... 7749 open("/tmp/vtc.7648.2c3869d9/v1//_.vsm_child/_.VSC_cluster.09720dc34dd3559c", O_RDONLY) = 21 7749 mmap(NULL, 4096, PROT_READ, MAP_SHARED, 21, 0x2000) = 0x7f09389d1000 Notice that we keep the mappings at one or two pages now and do not increase the length with the offset.
