My out of tree driver build is now reporting issues with the jump table:
./include/linux/jump_label.h: In function ‘jump_entry_code’:
./include/linux/jump_label.h:153:14: error: dereferencing pointer to incomplete
type ‘const struct jump_entry’
return entry->code;
^~
./include/linux/jump_label.h: In function ‘jump_entry_set_init’:
./include/linux/jump_label.h:180:7: error: dereferencing pointer to incomplete
type ‘struct jump_entry’
entry->key |= 2;
^~
./include/linux/jump_label.h: At top level:
./include/linux/jump_label.h:212:26: error: array type has incomplete element
type ‘struct jump_entry’
extern struct jump_entry __start___jump_table[];
^~~~~~~~~~~~~~~~~~~~
./include/linux/jump_label.h:213:26: error: array type has incomplete element
type ‘struct jump_entry’
extern struct jump_entry __stop___jump_table[];
^~~~~~~~~~~~~~~~~~~
This happens in v4.20-rc3 as well, so I bisected between v4.19 to
v4.20-rc1 which resulted in the following commit:
b34006c4258c9c86597b6b7123d6a9a3513d6cd7 is the first bad commit
commit b34006c4258c9c86597b6b7123d6a9a3513d6cd7

x86/jump_table: Use relative references
Initially I assumed this was my own fault, but my module does not have
these issues when using v4.19. Is there anything I should try/change in
my module makefile, includes, etc to support this relative reference
code?
Thank you,
Liam
