Subject: [PATCH v3 0/2] fs: avoid fdput() after failed fdget()
Date: Wed, 13 May 2020 17:33:19 -0600	[thread overview]
Message-ID: <cover.1589411496.git.skhan@linuxfoundation.org> (raw)

While debugging an unrelated problem, I noticed these two cases fdput()
is called after failed fdget() while reviewing at all the fdget() and
fdput() paths in the kernel.

Changes since v2:
Patches 1&2 changed to get rid of goto.

Changes since v1:
Patch 1:
  Changed to address review comments to refine the code for improved
  readability in addition to the change to avoid fdput() on failed
  fdget()
Patch 2:
  No change to v1. Including it in the series to keep the patches
  together.

Shuah Khan (2):
  fs: avoid fdput() after failed fdget() in ksys_sync_file_range()
  fs: avoid fdput() after failed fdget() in kernel_read_file_from_fd()
