Hans Reiser was convicted of [[murder]] on April 28, 2008, leaving the future of Reiser4 uncertain. After his arrest, employees of Namesys were assured they would continue to work and that the events would not slow down the software development in the immediate future. In order to afford increasing legal fees, Hans Reiser announced on December 21, 2006, that he was going to sell Namesys;<ref>{{cite web

In 2010, [[Phoronix]] wrote that Edward Shishkin was exploring options to get Reiser4 merged into Linux kernel mainline.<ref>{{cite web|url=https://www.phoronix.com/scan.php?page=news_item&px=NzY4OQ |title=Reiser4 May Go For Mainline Inclusion In 2010 |publisher=[[Phoronix]] |date=2009-11-10 |access-date= 2010-02-08}}</ref> {{As of|2019}}, the file system is still being updated for new kernel releases, but has not been submitted for merging.<ref name="phLinux5patch" /> In 2015, [[Michael Larabel]] mentioned it is unlikely to happen without corporate backing,<ref name=not-in-linux-4.0>{{cite web |url=https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.0-Missing-Features |author=Michael Larabel |date=23 February 2015 |title=KDBUS & Other Features You Won't Find In The Linux 4.0 Kernel |work=[[Phoronix]] }}</ref> and then he suggested in April 2019 that the main obstacle could be the renaming of Reiser4 to avoid reference to the initial author who was convicted of murder.<ref name="phLinux5patch" />
