Name

objfs– Kernel object filesystem

Description

The objfs filesystem describes the state of all modules currently loaded by the kernel. It is mounted during boot at /system/object.

The contents of the filesystem are dynamic and reflect the current state of the system. Each module is represented by a directory containing a single file, 'object.' The object file is a read only ELF file which contains information about the object loaded in the kernel.

The kernel may load and unload modules dynamically as the system runs. As a result, applications may observe different directory contents in /system/object if they repeatedly rescan the directory. If a module is unloaded, its associated /system/object files disappear from the hierarchy and subsequent attempts to open them, or to read files opened before the module unloaded, elicits an error.
