Subject: support splice reads on seq_file based procfs files v2
Hi Al,
Greg reported a problem due to the fact that Android tests use procfs
files to test splice, which stopped working with 5.10-rc1. This series
adds read_iter support for seq_file, and uses those for various seq_files
in procfs to restore splice read support.
Chances since v1:
- only switch a subset of proc files to use seq_read_iter
