This is what I wrote in the bug. /@ The matching code in configfs_readir() is:/ /@ name = configfs_get_name(next);/ /@ len = strlen(name);/ /@ if (next->s_dentry)/ /@ ino = next->s_dentry->d_inode->i_ino; <===/ /@ else/ /@ ino = iunique(configfs_sb, 2);/ /@ ./ /@ if (filldir(dirent, name, len, filp->f_pos, ino,/ /@ dt_type(next)) < 0)/ /@ return 0;/ /@ ./ /@ The oops indicates that next->s_dentry->d_inode is NULL./ Joel, does this give you any clues? BTW, thanks for the testcase. And yes, I can reproduce it easily. -------------- next part -------------- An HTML attachment was scrubbed...
