what is vmalloc?

[Antonio Olivares]

Dear all,

I am just recovering from the kernel panic, I saw when the system was booting, I saw something like ext4 malloc or something like that.  

I run 

[olivares at riohigh ~]$ dmesg | grep 'malloc'
    vmalloc : 0xe0800000 - 0xff3fe000   ( 491 MB)


What is vmalloc?

Is it virtual memory allocation?

Thanks,

Antonio
