Hello Community,<br>
<br>
I was browsing the tree and in slub.c/ function kfree(), I found "PageSlab"<br>
I could not find its definition anywhere.<br>
<br>
Also, googling about it did not yield much help except for pointers to<br>
various patches _using_ this.<br>
<br>
Can anyone explain what it is and where it is defined (if at all it<br>
has a definition).<br></blockquote><div><br></div><div><br></div><div>I am not sure what is your motive behind asking this question - PageSlab can mean many different thing, but one thing in common is the concept of SLAB allocator:</div>
