   4 Subject: [PATCH] linux_sysfs: Use pwrite/pread instead of 64bit versions
   5
   6 pread64/pwrite64 are aliased to pread/pwrite when largefile support is
   7 enabled e.g. using _FILE_OFFSET_BITS=64 macro
   8
   9 This helps it compile on latest musl C library based systems where these
  10 functions are put under _LARGEFILE64_SOURCE which is to be removed once
  11 all packages start using 64bit off_t, it works with glibc becuase
  12 _GNU_SOURCE feature macro also defines _LARGEFILE64_SOURCE, thats not
  13 the case with musl
