	Change	Effect
1	Field broken_body has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.
2	Field load_error has been removed from the middle position of this structural type.	1) Previous accesses of applications to the removed field will be incorrect. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

	Change	Effect
1	Field len has been removed from this type.	Applications will access incorrect memory when attempting to access this field.
2	Field offset has been removed from this type.	Applications will access incorrect memory when attempting to access this field.
3	Field pdata has been removed from this type.	Applications will access incorrect memory when attempting to access this field.
4	Field plen has been removed from this type.	Applications will access incorrect memory when attempting to access this field.
5	Field udata has been removed from this type.	Applications will access incorrect memory when attempting to access this field.
6	Field ulen has been removed from this type.	Applications will access incorrect memory when attempting to access this field.

libjio.h
[+] struct jtrans (6)

to the top

	Change	Effect
1	Size of this type has been changed from 32 bytes to 24 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Field broken_head has been renamed to broken.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field lock has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
2	Field op has been added to this type.	This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
3	Field buf has been renamed to numops.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	2nd parameter lenght has been renamed to length.	Renaming of a parameter may indicate a change in its semantic meaning.
