Hi Andrew, It looks like 2.13.0 is missing a few patches for 5.3. 7674f2c976744c38fd761518db92e01b22de2fbb (HEAD -> test) LU-12904 o2ib: ib_destroy_cq() returns void c22267e5a38c46a24ef3763131ee85cb57a16e5d LU-12904 build: account_page_dirtied is not exported e2735d07403c0cd533fe6ceac133a900871b3883 LU-12634 llite: Use __xa_set_mark if it is available ee3ecf5b6290081dff7c197b63b5087dcb299a9c LU-12634 libcfs: force_sig() removed task parameter a298f8c1376485512f83472a22dc755f47947e75 (tag: v2_13_0, tag: 2.13.0, origin/b2_13) New release 2.13.0
Will build on CentOS against 5.3.0 mainline kernel: $ git clean -dfx $ sh ./autogen.sh $ ./configure --disable-server --enable-client --with-linux=/usr/src/kernels/5.3.0-1.el7.x86_64 --disable-gss $ ./LUSTRE-VERSION-GEN 2.12.58_197_g7674f2c $ gcc --version gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39) If you are using gss then there are still 2 more patches pending to land on master that you will need to cherry-pick from gerrit: https://review.whamcloud.com/35743 https://review.whamcloud.com/36580 1735f8697a08d5edbf4a12dcfd402358dd4bfadb (in-review-gerrit) LU-12904 ldiskfs: Add ldiskfs support for linux 5.4 df0788accd0cb9260b3036b6f8a2b61a8122a56e LU-12904 gss: struct cache_detail readers changed to writers f206a46c127dfde490ce61080645b3ee2b1d3127 LU-12634 gss: uid_keyring and session_keyring moved 9fb6818fe3d1e0130e147c5cf740e5e9a2631166 (origin/master, origin/HEAD, lunar/master, master) LU-12787 tests: skip project quota if it is disabled On top of 2.13.0 tag: 305cadaa77de8833a5eb501389742bfb5584410f (HEAD -> test) LU-12904 gss: struct cache_detail readers changed to writers 6bf763bf35559a5008077ee37ba74d0075c1604a LU-12634 gss: uid_keyring and session_keyring moved 7674f2c976744c38fd761518db92e01b22de2fbb LU-12904 o2ib: ib_destroy_cq() returns void c22267e5a38c46a24ef3763131ee85cb57a16e5d LU-12904 build: account_page_dirtied is not exported e2735d07403c0cd533fe6ceac133a900871b3883 LU-12634 llite: Use __xa_set_mark if it is available ee3ecf5b6290081dff7c197b63b5087dcb299a9c LU-12634 libcfs: force_sig() removed task parameter a298f8c1376485512f83472a22dc755f47947e75 (tag: v2_13_0, tag: 2.13.0, origin/b2_13) New release 2.13.0 a4af7575718a06169866cc11e7b6cdfa266d44e1 LU-13030 pcc: Init saved dataset flags properly $ git clean -dfx $; sh ./autogen.sh $ ./configure --disable-server --enable-client --with-linux=/usr/src/kernels/5.3.0-1.el7.x86_64 $ make -j16 $ ./LUSTRE-VERSION-GEN 2.12.58_199_g305cada Depending on the version of gcc you are using you may need to grab some of the gcc8 fixes as well. I’m thinking of this one: LU-12904 build: Support for gcc -Wimplicit-fallthrough And possibly this one: LU-12904 build: External _module_ decorator removed If should also get you up to mainline 5.4 (depending on what patches have been pulled into you 5.3 kernel). This ‘error: "___wait_var_event" redefined [-Werror]’ I have not seen .. if you are still seeing this it would help if you include the exact kernel version and configure that you are working with.
