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.
