This FS stacks transparently over existing sub-tree of any 'real' FS and provides some special functionality via ioctl() calls. Here is a question that arised to me regarding the VFCF_LOOPBACK flag. The comment in states that this flag means that the FS is aliasing some other one. On the other hand, in my case no aliasing is done (since I'm mounting transparently and do not create new name space). So, should I specify the flag in VFS_SET() macro? Any hints will be greatly appretiated. Thank you in advance, sincerely, Ilya. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
