The following options will be removed:
innodb_file_format
innodb_file_format_check
innodb_file_format_max
innodb_large_prefix
They have been deprecated in MySQL 5.7.7 (and MariaDB 10.2.2) in WL#7703.
The file_format column in two INFORMATION_SCHEMA tables will be removed:
innodb_sys_tablespaces
innodb_sys_tables
Code to update the file format tag at the end of page 0:5
(TRX_SYS_PAGE in the InnoDB system tablespace) will be removed.
When initializing a new database, the bytes will remain 0.
All references to the Barracuda file format will be removed.
Some references to the Antelope file format (meaning
ROW_FORMAT=REDUNDANT or ROW_FORMAT=COMPACT) will remain.
This basically ports WL#7704 from MySQL 8.0.0 to MariaDB 10.3.1:

contains a bad and a good copy
Clean up the InnoDB doublewrite buffer code.
buf_dblwr_init_or_load_pages(): Do not add empty pages to the buffer.
buf_dblwr_process(): Do consider changes to pages that are all zero.
Do not abort when finding a corrupted copy of a page in the doublewrite
buffer, because there could be multiple copies in the doublewrite buffer,
and only one of them needs to be good.
The test case deliberately crashes the server. If this crash happens in the
middle of a page write, InnoDB crash recovery recovers the page from the
doublewrite buffer, writing a message to the error log that is flagged as a
test failure by mysql-test-run. So add a suppression for this.
Adjust full test suite to work with GTID.
Huge patch, mainly due to having to update .result file for all SHOW BINLOG
EVENTS and mysqlbinlog outputs, where the new GTID events pop up.
Everything was painstakingly checked to be still correct and valid .result
file updates.
Keep track of how many pending XIDs (transactions that are prepared in
storage engine and written into binlog, but not yet durably committed
on disk in the engine) there are in each binlog.
When the count of one binlog drops to zero, write a new binlog checkpoint
event, telling which is the oldest binlog with pending XIDs.
When doing XA recovery after a crash, check the last binlog checkpoint
event, and scan all binlog files from that point onwards for XIDs that
must be committed if found in prepared state inside engine.
Remove the code in binlog rotation that waits for all prepared XIDs to
be committed before writing a new binlog file (this is no longer necessary
when recovery can scan multiple binlog files).
