[PATCH 6.1 041/197] parisc: Prevent hung tasks when printing inventory on serial console

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Helge Deller <deller@xxxxxx>

commit c8708d758e715c3824a73bf0cda97292b52be44d upstream.

Printing the inventory on a serial console can be quite slow and thus may
trigger the hung task detector (CONFIG_DETECT_HUNG_TASK=y) and possibly
reboot the machine. Adding a cond_resched() prevents this.
