How file system is represented in the kernel? The kernel keeps track of files using in-core inodes (“index nodes”), usually derived by the low-level filesystem from on-disk inodes. A file may have several names, and there is a layer of dentries (“directory entries”) that represent pathnames, speeding up the lookup operation.
Are file systems part of the kernel? The filesystem drivers are, indeed, part of the operating system, although they are usually distinct and separate from the operating system kernel.
How do I know if my kernel is tainted? To know if a running kernel is tainted or not, check the numerical value in the file /proc/sys/kernel/tainted. Non-zero if the kernel has been tainted. Numeric values, which can be checked: 1 – A module with a non-GPL license has been loaded, this includes modules with no license.
What causes a tainted kernel? The primary reason for the ‘Tainted: ‘ string is to tell kernel debuggers if this is a clean kernel or if anything unusual has occurred. Tainting is permanent: even if an offending module is unloaded, the tainted value remains to indicate that the kernel is not trustworthy.
