Wong" , Linux Kernel Mailing List , linux-xfs , Eric Sandeen Hi Linus, I've got one more bug fix for xfs for 4.17-rc4, which caps the amount of data we try to handle in one dedupe request so that userspace can't livelock the kernel. This series has been run through a full xfstests run during the week and through a quick xfstests run against this morning's master, with no ajor failures reported. Let me know if there are any merge problems. --D The following changes since commit 7b38460dc8e4eafba06c78f8e37099d3b34d473c: xfs: don't fail when converting shortform attr to long form during ATTR_REPLACE (2018-04-17 19:10:15 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/xfs-4.17-fixes-2 for you to fetch changes up to 021ba8e98fe5c6691b3cc3669faafa02403aa211: xfs: cap the length of deduplication requests (2018-05-02 09:21:33 -0700) ---------------------------------------------------------------- Changes since last update: - Cap the maximum length of a deduplication request at MAX_RW_COUNT/2 to avoid kernel livelock due to excessively large IO requests. ---------------------------------------------------------------- Darrick J.
