hi folks,
i am confused with the functions starting from vfs_ . i think they show the significance of VFS model i mean if something could be done without touching the disk stuff then why not to do that but i am not quite sure. so please help me understand what does these actually mean??
thanks in advance guysss
well by something i mean , that some process needs to access the offset of file for next read or dup that file discriptor so why each time to go for inode . (check me if i am wrong) m sorry for not being clear in textual work. but i got it now . thank u for noticing this query.
I am not sure that I understand the above question correctly, you mean "what is the use of VFS file system if doing operation without touching the disk . That means doing operation on cd rom, keyboard,mouse ?"
VFS is a upper layer of all the filesystem and all the module register its file operation into this layer. So Whenever you doing operation on any file, VFS layer receive the request and redirect into corresponding registered module operation.
I don't think we can do the operation without vfs.
Please correct me if i am wrong.
Thanks , Skm prabhu
