Yes, I think we'd better to use erofs_kmalloc(). :) Actually, fault injection in erofs_kmalloc only affect erofs module, we can expect that the range of fault can be limited in erofs code, rather than whole kernel, so the test point can be aimed at more accurately. > > The fault injection subsystem was introduced in the initial upstreamed > EROFS version, which is taken from f2fs by Chao Yu. > > Fault injection is important to test fs..
