question about alloc_bootmem

[javaweb zhang <javawebzwp@xxxxxxxxx>]

Hello, everyone. I use alloc_bootmem() in profile.c to allocate a big memory at function profile_init(), how I know whether it is success? The following is my code:

// at kernel/profile.c

ctxsw_A = (struct ctxsw_rec *)alloc_bootmem(sizeof(struct ctxsw_rec)*CTXSW);

ctxsw_rec is a struct which declared in include/linux/profile.h,  CTXSW = 4>>10
