kernel/module.c: Update debug alignment after symtable generation (168e47f2) · Commits · 戴 / test

When CONFIG_DEBUG_SET_MODULE_RONX is enabled, the sizes of module sections are aligned up so appropriate permissions can be applied. Adjusting for the symbol table may cause them to become unaligned. Make sure to re-align the sizes afterward. Signed-off-by:
