RE: [PATCH] swiotlb: Do not set total_used to 0 in swiotlb_create_debugfs_files()

From: Easwar Hariharan eahariha@linux.microsoft.com Sent: Friday, March 29, 2024 12:47 PM [...] Sorry, I'm missing a why in this commit message. Can you say what happens if the total_used and used_hiwater IS blindly set to 0? Is the only effect the change in the readout of the swiotlb debugfs files?

Thanks, Easwar

Right, when the system is not doing any I/O, the readout may return a huge number while it should return 0. This is the only effect.

Thanks, Dexuan
