Subject: [PATCH v2 0/2] fs: avoid fdput() after failed fdget()
Date: Tue, 12 May 2020 13:43:03 -0600	[thread overview]
Message-ID: <cover.1589311577.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 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()
