crypt_stat memory itself is allocated when inode is created, in ecryptfs_alloc_inode, which returns NULL on failure and is handled by callers, which would prevent us getting to this point. It then calls ecryptfs_init_crypt_stat which allocates crypt_stat->tfm checking for and likewise handling allocation failure. Finally, crypt_stat->flags has ECRYPTFS_STRUCT_INITIALIZED merged into it in ecryptfs_init_crypt_stat as well. Simply put, the conditions that the BUG_ON checks for will never be triggered, as to even get to this function, the relevant conditions will have already been fulfilled (or the inode allocation would fail in the first place and thus no call to this function or those above it).
