Doubt regarding PageLocked in Linux kernel source

[Shashidhara Shamaiah]

Hi,

 

I was looking at the source file fs/jbd/transaction.c . In the function
journal_invalidatepage the code calls the macro

PageLocked . I need to look at its implementation. I could locate where
the definition of PageLocked. Its not a function  as its absent in the
System.map file.  I have searched in internet. It was defined as a macro
in older kernels. But I could not get its definition in the recent
kernels. Please point me to the right direction.

 

Regards

Shashidhara
