Subject: [GIT PULL] overlayfs update for 5.6
Date: Tue, 4 Feb 2020 10:37:58 +0100 [thread overview]
Message-ID: <20200204093758.GA7822@miu.piliscsaba.redhat.com> (raw)
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
