Problems with Data Types, High Severity (1)

	Change	Effect
1	Field apply_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.

libjio.h
[+] struct jfsck_result (1)

to the top

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Parameter flags of type unsigned int has been added to the calling stack.	This parameter will not be initialized by old clients.

libjio.h, libjio.so
[+] jtrans_new ( jfs_t* fs ) (1)

to the top

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of this type has been changed from 28 bytes to 24 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

libjio.h
[+] struct jfsck_result (1)

to the top

Problems with Symbols, Low Severity (1)

	Change	Effect
1	Type of 4th parameter jflags has been changed from int to unsigned int.	Replacement of parameter data type may indicate a change in its semantic meaning.

libjio.h, libjio.so
[+] jopen ( char const* name, int flags, int mode, int jflags ) (1)

to the top

Problems with Constants, Low Severity (1)

	Change	Effect
1	The constant J_NOCLEANUP with value 1 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

libjio.h
[+] J_NOCLEANUP

to the top

Other Changes in Data Types (1)

	Change	Effect
1	The member J_EIO with value -5 has been added.	No effect.

libjio.h
[+] enum jfsck_return (1)

to the top

Other Changes in Constants (1)

	Change	Effect
1	The constant J_CLEANUP with value 1 has been added.	No effect.
