If a mount fails, mounting a romfs still modify cyg_mtab_entry->data. With the patch included, cyg_mtab_entry->data is only modified after a succesful mount. This makes the following codepath impossible: char address[16]; sprintf( address, "%p", ROMDIR_ADDR); err = mount( address, "rom", "romfs" ); if( err < 0 ) { // if no ROM fs has been written, we use a default one. sprintf( address, "%p", _binary___mkromfs_rom_rawdata_start); err = mount( address, "rom", "romfs" ); if (err<0) { // unrecoverable failure
