Merge tag 'ovl-update-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs
Pull overlayfs update from Miklos Szeredi:
- Try to preserve holes in sparse files when copying up, thus saving
disk space and improving performance.
- Fix a performance regression introduced in v4.19 by preserving
asynchronicity of IO when fowarding to underlying layers. Add VFS
helpers to submit async iocbs.
- Fix a regression in lseek(2) introduced in v4.19 that breaks >2G
seeks on 32bit kernels.
- Fix a corner case where st_ino/st_dev was not preserved across copy
up.
- Miscellaneous fixes and cleanups.
