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()
