Series fs: Hole punch vs page cache filling races | expand

Commit Message

Jan Kara May 12, 2021, 1:46 p.m. UTC
Use invalidate_lock instead of f2fs' private i_mmap_sem. The intended
purpose is exactly the same. By this conversion we fix a long standing
race between hole punching and read(2) / readahead(2) paths that can
lead to stale page cache contents.
