yes, this is related to mtab patch, but it mounted it anyway. I was able 
to reproduce this warning. It should not affect smb+ecryptfs data 
corruption in any way. Btw, did you test if this version works in 
valgrind or not? (the "Source and destination overlap in memcpy" warning).

btw, we should move this conversation off list if it's related only to 
ecryptfs.
