Subject: [PATCH v2 0/2] Switching ARC to optimized generic strncpy_from_user
Date: Wed, 15 Jan 2020 16:21:22 -0800 [thread overview]
Message-ID: <20200116002124.17988-1-vgupta@synopsys.com> (raw)
Hi,
This series switches ARC to generic word-at-a-time interface.
I understand that going fwd, we may drop the inline versions altogether but this
helps ARC code in the interim.
v2 <- v1
- Moved __strnlen_user/__strncpy_from_user to under ifdef gaurd [Arnd]
- Dropped the broken optimization patch [Linus]
- Folded 2 ARC patches into 1
Thx,
-Vineet
