Comment 9 for bug 509180

Hey Erik - thanks for the *great* report!

So the eCryptfs inode's i_size is out of sync from what is stored in the eCryptfs metadata (the first 8 bytes of the encrypted file). Some initial guesses are that we're missing an i_size_write() somewhere (maybe down an error path?) or we could be incorrectly passing the lower inode's i_size to i_size_write() since the upper and lower i_sizes are the same.

Are you seeing any eCryptfs error messages in the logs? I'll begin looking at the suspect code paths.
