Hi All
I am working on tmpfs. During code analysis I found shmem driver register itself as tmpfs .
cat /proc/meminfo Shmem field read NR_SHMEM enum filed and shows used memory in tmpfs
[root@localhost linux-3.8.2]# cat /proc/meminfo | grep -r Shmem Shmem: 704 kB [root@localhost linux-3.8.2]#
include/linux/mmzone.h enum zone_stat_item { -----cut here------- NR_SHMEM, /* shmem pages (included tmpfs/GEM pages -----cut here }
I have the following query 1-> cat /proc/meminfo | grep -r Shmem show only the used tmpfs memory or it show used tmpfs memory + mata data also (because I found Shmem is bit larger then tempfs used memory ) 2-> as per the developer comments NR_SHMEM included tmpfs and GEM pages whct is Gem pages 3-> is my above code analysis is correct?
