Bio flags

[Praveen Kumar]

Hi,

I am porting some of  file system related code from 3.0.101 kernel to
4.4.13 kernel and found that the number of bio flags have been reduced from
13 to 8 and some of the which been removed are :

BIO_UPTODATE
BIO_RW_BLOCK
BIO_EOF
BIO_EOPNOTSUPP
...

I was unable to find much in the documentation sections regarding the flags.
Can someone please help providing inputs or pointers over this change.

Thank you for your help.

Regards,

~Praveen.
