For the ext file system debugger, see e2fsprogs.

debugfs is a special file system available in the Linux kernel since version 2.6.10-rc3.[1] It was written by Greg Kroah-Hartman.[2]

debugfs is a simple-to-use RAM-based file system specially designed for debugging purposes. It exists as a simple way for kernel developers to make information available to user space.[3] Unlike /proc, which is only meant for information about a process, or sysfs, which has strict one-value-per-file rules, debugfs has no rules at all. Developers can put any information they want there.[4]

Use

[edit]

To compile a Linux kernel with the debugfs facility, the CONFIG_DEBUG_FS option must be set to yes. It is typically mounted at /sys/kernel/debug with a command such as:[5] 

mount -t debugfs none /sys/kernel/debug

It can be manipulated using several calls from the C header file linux/debugfs.h, which include:

  • debugfs_create_file – for creating a file in the debug filesystem.
  • debugfs_create_dir – for creating a directory inside the debug filesystem.
  • debugfs_create_symlink – for creating a symbolic link inside the debug filesystem.
  • debugfs_remove – for removing a debugfs entry from the debug filesystem.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
