Subject: [PATCH] src/shared/missing.h: fix getrandom system call number on
|
||
|
|
ARM64
|
||
|
|
|
||
|
|
The getrandom() system call number is indeed 384 on ARM, but it is not
|
||
|
|
the same on ARM64. ARM64 uses the asm-generic headers, including for
|
||
|
|
system call numbers, so the getrandom() system call number on ARM64 is
|
||
|
|
278. This fixes runtime issues of eudev on ARM64, such as:
|
||
|
|
|
||
|
|
Populating /dev using udev: [ 6.186817] udevd[1204]: starting version 3.1.5
