Hello Community,
I was browsing the tree and in slub.c/ function kfree(), I found "PageSlab"

Also, googling about it did not yield much help except for pointers to
various patches _using_ this.
Can anyone explain what it is and where it is defined (if at all it

And this page is for detailed description on SLAB:
http://lwn.net/Articles/320556/ (several variation of SLAB described, including the SLUB u mentioned above).
which is used in several OS (Unix mainly).
and this blog teaches u how to analyze SLAB usage patterns:
etc...
