For example, to get the status information of a process, all you have to do is
mounts Mounted filesystems
net Networking info (see text)
partitions Table of partitions known to the system
- pci Depreciated info of PCI bus (new way -> /proc/bus/pci/,
+ pci Deprecated info of PCI bus (new way -> /proc/bus/pci/,
decoupled by lspci (2.4)
rtc Real time clock
scsi SCSI info (see text)
Because the NMI watchdog shares registers with oprofile, by disabling the NMI
watchdog, oprofile may have more registers to utilize.
+maps_protect
+------------
+
+Enables/Disables the protection of the per-process proc entries "maps" and
+"smaps". When enabled, the contents of these files are visible only to
+readers that are allowed to ptrace() the given process.
