I was wondering how Linux decide to free an inode from the inode_cache? If a file is open, an inode structure will be created and put into the inode_cache, but when will this inode be free and removed from the inode_cache? after this file is closed? If so, this seems to be inefficient. Can someone tell me how Linux handle this issue?
