Hi all,

Is there any updated documentation about d_revalidation() flags usage? 
It seems is not quite clear on just following the code in fs/namei.c and 
what is it going to do. I don't understand why invalidates a dentry will 
cause a ESTALE in the vfs in namei.c and whats the purpose of ESTALE 
instead of a lookup since isn't it the purpose of d_revalidate()?

regards,
David Chow
