While reading the code of struct dentry_operations of wrapfs, I found out that the operations involved don't do anything to the wrapfs dentry cache, these operations only deal with the actual fs dcache using actual fs dentry operations. (3) When I update some file in the actual fs e.g. a file in the folder on ext3 file system, the changes done there are not reflected on the same file on wrapper fs but the vice versa is working correctly. I want some details regarding these questions. Hope I am able to convey my point. Thanks, Uzair Lakhani, Karachi, Pakistan. __________________________________________________ Do You Yahoo!?
