Subject: [PATCH 0/3] btrfs: fix fsync failure with SQL Server workload
Date: Mon, 24 May 2021 11:35:52 +0100	[thread overview]
Message-ID: <cover.1621851896.git.fdmanana@suse.com> (raw)

From: Filipe Manana <fdmanana@suse.com>

This patchset fixes a fsync failure (-EIO) and transaction abort during
a workload for Microsoft's SQL Server running in a Docker container as
reported at:

https://lore.kernel.org/linux-btrfs/93c4600e-5263-5cba-adf0-6f47526e7561@in.tum.de/

It also adds an optimization for the workload, by removing lots of fsyncs
that trigger the slow code path and replacing them with ones that use the
fast path, reducing the workload's runtime by about -12% on my test box.

Filipe Manana (3):
  btrfs: fix fsync failure and transaction abort after writes to
    prealloc extents
  btrfs: fix misleading and incomplete comment of btrfs_truncate()
  btrfs: don't set the full sync flag when truncation does not touch
    extents
