As expected I get two merge conflicts as my patches update code which u have removed. But looks straight forward to resolve. Meaning we can carry respective patches and give Linus a heads up abt the merge conflict. There's also a fixup needed for ARC to remove the pmdp splitting assuming ARC THP makes it into mainline first. -Vineet > >> Given people rebase off of mmtomm would it be better if generic patches went thru >> Andrew and probably included sooner for 4.4 target ? >> >> -Vineet >> >> -- >> To unsubscribe, send a message with 'unsubscribe linux-mm' in >> the body to majordomo@xxxxxxxxx.
