| |
Hi,
I am seeing a kernel panic in cifs module. It seems to be a result of invalid inode entry in dentry for the file it is trying to validate.
The inode->i_ino is set zero and inode->i_mapping is set to NULL in the inode pointer in the dentry (0xdf8ea200) structure. I went through the cifs code and could not find any valid case that could trigger this situation. Is there any case which can lead to this situation?
