| |
Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs.git tags/ovl-update-5.6
- Try and 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.
Thanks, Miklos
