<bits/syscall.h>: Use an arch-independent system call list on Linux
|
||||
|
||||
This commit changes the way the list of SYS_* system call macros
|
||||
is created on Linux. glibc now contains a list of all known system
|
||||
calls, and the generated <bits/syscall.h> file defines the SYS_
|
||||
macro only if the correspnding __NR_ macro is defined by the kernel
|
||||
headers.
|
||||
|
||||
As a result, there glibc does not have to be rebuilt to pick up
|
||||
system calls if the glibc sources already know about them. This
|
||||
means that glibc can be built with older kernel headers, and if
|
||||
the installed kernel headers are upgraded afterwards, additional
|
||||
SYS_ macros become available as long as glibc has a record for
|
||||
those system calls.
|
||||
|
||||
The explicit system call list for system call management was not
|
||||
accepted upstream.
