- Various driver bug fixes in mlx5, mlx4, bnxt_re and qedr, ranging from bugs under load to bad error case handling - There in one largish patch fixing the locking in bnxt_re to avoid a machine hard lock situation - A few core bugs on error paths - A patch to reduce stack usage in the new CQ API - One mlx5 regression introduced in this merge window - There were new syzkaller scripts written for the RDMA subsystem and we are fixing issues found by the bot - One of the commits (aa0de36a40f4 “RDMA/mlx5: Fix integer overflow while resizing CQ”) is missing part of the commit log message and one of the SOB lines. The original patch was from Leon Romanovsky, and a cut-n-paste separator in the commit message confused patchworks which then put the end of message separator in the wrong place in the downloaded patch, and I didn’t notice in time. The patch made it into the official branch, and the only way to fix it in-place was to rebase. Given the pain that a rebase causes, and the fact that the patch has relevant tags for stable and syzkaller, a revert of the munged patch and a reapplication of the original patch with the log message intact was done. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJaoxYpAAoJELgmozMOVy/dPeoQAKUvtJzWaceuKdmNgh+Ut0qZ ZpaZIUwZsrrZAPOraxy36Q35vlzeb3AWLust3xTIHtb00tB55wgrWXo1KOPX4MhH AXDHCaYdjSdKewGo15zYXKAROs/BQ+ypoc3/jneqttTRtD0C93n0FpHb27k593Pu WzuvtqzVvLe11/IYk/lzlVHLuQRI1HIhUa2ygG/cFl1vLOcF1eY8Z+MdCS79uvv1 s0FDB6yhIEcNaXGcDpIfQ6cJLVxLqBlvyCMB7Tok6Ss8Xk6383ZxXY/FrLkCMTo/ rMiiWp9yhQ4hl+7NuO/KUWoeFuswjZso2vzerTe0DKdvAHO8fNNuC/Y6SuliEim7 So7XVAFa0PArxw+/6sr8+nHkH0+O785xPU4qTgMRb9LyDw/Te7st1BHGJLuoNdER SM8LHKCd0LvP2hvi8fQpJNzfAqexaiJYqZlI3n+VdfyMZw6+IG8gGeNMQ1fKStF6 rUve9+h91h7rW6W+jXOQwsMiMfSJLiKwtjapo6HRKYS3FUVd/wIdbjkNIc7rmgUy KI3zLanyfzOCFN5W8w4BBud25ibmxxuQMsZgx4oQUVYFWgosnQqTCAUNVlT2Pxou 33yoWiwwcWZG3ATa5EfIBl1anqQP+mq7DxfQ6a/j1PNDl2Dh4DHWW1qwlhuIK8EU BYqPcWOFdk+DgGMjDJju =ZvN0 -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma Pull rdma fixes from Doug Ledford: - Various driver bug fixes in mlx5, mlx4, bnxt_re and qedr, ranging from bugs under load to bad error case handling - There in one largish patch fixing the locking in bnxt_re to avoid a machine hard lock situation - A few core bugs on error paths - A patch to reduce stack usage in the new CQ API - One mlx5 regression introduced in this merge window - There were new syzkaller scripts written for the RDMA subsystem and we are fixing issues found by the bot - One of the commits (aa0de36a40f4 “RDMA/mlx5: Fix integer overflow while resizing CQ”) is missing part of the commit log message and one of the SOB lines.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
