+Subject: [PATCH] compiler: Change LLVM targets
+
+ - Change x86_64-unknown-linux-gnu to use x86_64-pc-linux-gnu
+ - Change i686-unknown-linux-gnu to use i686-pc-linux-gnu
+
+Reintroduce the aliasing that was removed in 1.52.0 and alias the -pc-
+triples to the -unknown- triples. This avoids defining proper -pc-
+targets, as things break when this is done:
+
+ - The crate ecosystem expects the -unknown- targets. Making -pc-
+   rustc's host triple (and thus default target) would break various
+   crates.
+ - Firefox's build breaks when the host triple (from
+   `rustc --version --verbose`) is different from the target triple
+   (from `rustc --print target-list`) that best matches autoconf.

+Subject: [PATCH] [sanitizer] Remove #include <linux/fs.h> to resolve
+ fsconfig_command/mount_attr conflict with glibc 2.36
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It is generally not a good idea to mix usage of glibc headers and Linux UAPI
+headers (https://sourceware.org/glibc/wiki/Synchronizing_Headers). In glibc
+since 7eae6a91e9b1670330c9f15730082c91c0b1d570 (milestone: 2.36), sys/mount.h
+defines `fsconfig_command` which conflicts with linux/mount.h:
+
+    .../usr/include/linux/mount.h:95:6: error: redeclaration of ‘enum fsconfig_command’
+
+Remove #include <linux/fs.h> which pulls in linux/mount.h. Expand its 4 macros manually.
+Android sys/mount.h doesn't define BLKBSZGET and it still needs linux/fs.h.
+In the long term we should move Linux specific definitions to sanitizer_platform_limits_linux.cpp
+but this commit is easy to cherry pick into older compiler-rt releases.
