| |
Hi
I found when I enable CONFIG_ENABLE_VMALLOC_SAVING on ARM arch, Vmalloc still only use VMALLOC_START -- VMALLOC_END virtual address, It don't use the memory hole address, Only function call get_vm_area_caller like ioremap can use These memory hole address .
Why not change vmalloc also use this address?
Another problem is that when I cat /proc/meminfo , The VmallocTotal item show doesn't include memory hole address, It only show VMALLOC_START -- VMALLOC_END , I think it is not correct here , should add memory hole as vmalloc when CONFIG_ENABLE_VMALLOC_SAVING is enabled , isn't it ?
Thanks
