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.
Yes, it's not a function, it's a macro. Page flags are cleverly implemented in the Linux kernel as macros. You wont be able to cscope into it. See http://lxr.linux.no/linux+v3.3.2/include/linux/page-flags.h for implementation details.
