Hi, I've found something peculiar while I was testing v3.11: There's a lot of directory missing (actually hiding) in /proc :
/proc/sys/, /proc/fs/, /proc/bus/ etc... all the directories that are not PIDs are in "stealth mode": they don't appear with an ls (nor a find), but I can list their contents. I've bisecting that to the commit f0c3b5093addc8bfe9fe3a5b01acb7ec7969eafa ( [readdir] convert procfs ) This happens on nfsroot, but also on UBIFS. Here are my platform details: - arm (at91sam9g35-ek) - defconfig attached - using uImage and at91sam9g35ek.dtb - libuClibc-0.9.33.2.so # ls -l /proc/ total 0 dr-xr-xr-x 7 root root 0 Dec 31 17:00 1/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 121/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 123/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 125/ dr-xr-xr-x 7 root root 0 Dec 31 17:15 1306/ dr-xr-xr-x 7 root root 0 Dec 31 17:15 1307/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 2/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 236/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 237/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 242/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 243/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 244/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 245/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 3/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 313/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 314/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 326/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 328/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 331/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 361/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 362/ dr-xr-xr-x 7 dbus dbus 0 Dec 31 17:00 364/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 372/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 376/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 378/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 389/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 390/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 5/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 6/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 7/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 8/ dr-xr-xr-x 7 root root 0 Dec 31 17:00 9/ -r--r--r-- 1 root root 0 Dec 31 17:15 buddyinfo -r--r--r-- 1 root root 0 Dec 31 17:15 cmdline -r--r--r-- 1 root root 8478 Dec 31 17:15 config.gz -r--r--r-- 1 root root 0 Dec 31 17:15 consoles -r--r--r-- 1 root root 0 Dec 31 17:15 cpuinfo -r--r--r-- 1 root root 0 Dec 31 17:15 crypto -r--r--r-- 1 root root 0 Dec 31 17:15 devices -r--r--r-- 1 root root 0 Dec 31 17:15 diskstats -r--r--r-- 1 root root 0 Dec 31 17:15 filesystems -r--r--r-- 1 root root 0 Dec 31 17:15 interrupts -r--r--r-- 1 root root 0 Dec 31 17:15 kallsyms -r--r--r-- 1 root root 0 Dec 31 17:15 key-users -r-------- 1 root root 0 Dec 31 17:15 kmsg -r-------- 1 root root 0 Dec 31 17:15 kpagecount -r-------- 1 root root 0 Dec 31 17:15 kpageflags -r--r--r-- 1 root root 0 Dec 31 17:15 loadavg -r--r--r-- 1 root root 0 Dec 31 17:15 locks -r--r--r-- 1 root root 0 Dec 31 17:15 meminfo -r--r--r-- 1 root root 0 Dec 31 17:15 pagetypeinfo -r--r--r-- 1 root root 0 Dec 31 17:15 partitions lrwxrwxrwx 1 root root 0 Dec 31 17:00 self -> 1307/ -r-------- 1 root root 0 Dec 31 17:15 slabinfo -r--r--r-- 1 root root 0 Dec 31 17:15 softirqs -r--r--r-- 1 root root 0 Dec 31 17:15 stat --w------- 1 root root 0 Dec 31 17:15 sysrq-trigger -r--r--r-- 1 root root 0 Dec 31 17:15 timer_list -r--r--r-- 1 root root 0 Dec 31 17:15 uptime -r--r--r-- 1 root root 0 Dec 31 17:15 version -r-------- 1 root root 0 Dec 31 17:15 vmallocinfo -r--r--r-- 1 root root 0 Dec 31 17:15 vmstat -r--r--r-- 1 root root 0 Dec 31 17:15 zoneinfo # ls -ld /proc/sy* --w------- 1 root root 0 Dec 31 17:15 /proc/sysrq-trigger # ls -ld /proc/sys dr-xr-xr-x 1 root root 0 Dec 31 17:00 /proc/sys/ # ls -l /proc/sys/ total 0 dr-xr-xr-x 1 root root 0 Dec 31 17:16 debug/ dr-xr-xr-x 1 root root 0 Dec 31 17:16 dev/ dr-xr-xr-x 1 root root 0 Dec 31 17:16 fs/ dr-xr-xr-x 1 root root 0 Dec 31 17:00 kernel/ dr-xr-xr-x 1 root root 0 Dec 31 17:00 net/ dr-xr-xr-x 1 root root 0 Dec 31 17:16 vm/ # uname -a Linux LNS 3.10.0-rc6-00032-gf0c3b50 #34 Mon Aug 12 15:30:14 CEST 2013 armv5tejl GNU/Linux # cat /proc/cmdline console=ttyS0,115200 loglevel=8 ip=dhcp root=/dev/nfs nfsroot=10.128.0.9:/nfsroot,v3 Best regards, Richard.
