Hi, please consider pulling a fix for btrfs. This time it's really a one-liner and prevents leaking an internal error value 1 out of the ftruncate syscall.
This has been observed in practice. The steps to reproduce make a common pattern (open/write/fync/ftruncate) but also need the application to not check only for negative values and happens only for compressed inlined files. The conditions are narrow but as this could break userspace I think it's better to merge it now and not wait for the merge window. Thanks. ---------------------------------------------------------------- The following changes since commit 02ee654d3a04563c67bfe658a05384548b9bb105: btrfs: fix crash when trying to resume balance without the resume flag (2018-05-17 14:38:24 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux.git for-4.17-rc6-tag for you to fetch changes up to d50147381aa0c9725d63a677c138c47f55d6d3bc: Btrfs: fix error handling in btrfs_truncate() (2018-05-24 11:56:57 +0200) ---------------------------------------------------------------- Omar Sandoval (1): Btrfs: fix error handling in btrfs_truncate() fs/btrfs/inode.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
