6 objfs - Kernel object filesystem
7
9 The objfs filesystem describes the state of all modules currently
10 loaded by the kernel. It is mounted during boot at /system/object.

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

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