After this patchset, page_frag is a small subsystem/library
on its own, so add an entry in MAINTAINERS to indicate the
new subsystem/library's maintainer, maillist, status and file
lists of page_frag.

Alexander is the original author of page_frag, add him in the
MAINTAINERS too.

The bar for maintaining core code is very high, if you'd 
like to be a maintainer please start small.

I did start small with the page_pool case, as mentioned in
[1] of a similar comment, and the page_frag is a small
subsystem/library as mentioned in commit log.

I think I still might need a second opinion here.

Please note that the 'small' part here does not refer strictly to code 
size. Any core networking code has the bar significantly higher than 
i.e. NIC drivers - even if the latter could count order of magnitude 
more LoC.
AFAICS there is an unwritten convention that people are called to 
maintain core code, as opposed to people appointing themself to maintain 
driver code.

Cheers,

Paolo

Is there any discussion that is referring to above 'unwritten convention'?
As my pool community experience tells me the above 'unwritten
convention' is mainly referring to well-established subsystem that is
already in the MAINTAINERS, and page_frag is not really a subsystem or
library before this patchset, it seems common to me that someone being
willing and able to turn it into a subsystem or library might become the
co-maintainer if she/he is also willing to co-maintain it.
