[PATCH] initialize parts of udf inode earlier in create
Eric says: > I saw an oops down this path when trying to create a new file on a UDF > filesystem which was internally marked as readonly, but mounted rw: > > udf_create > udf_new_inode > new_inode > alloc_inode > udf_alloc_inode > udf_new_block > returns EIO due to readonlyness > iput (on error) I ran into the same issue today, but when listing a directory with invalid/corrupt entries: udf_lookup udf_iget get_new_inode_fast alloc_inode udf_alloc_inode __udf_read_inode fails for any reason iput (on error) ... The following patch to udf_alloc_inode() should take care of both (and other similar) cases, but I've only tested it with udf_lookup().
