which "the" filesystem?
*root filesystem*. The file system whose root directory is root of the
system's directory tree.
My main concern is :
When I have dentry object of a file. Can I traverse till root's dentry
using dentry->d_parent, step by step?
How does kernel shrinks dentry cache? Does it removes any of the dentry
which is in 'parent path' of the concerned dentry object?
If kernel can remove such parent dentry, what happens when I access
dentry->d_parent.
Thanks,
- Ashish K.
