Now that the xattr handler is passed to the xattr handler operations, we
have access to the attribute name prefix, so simplify
f2fs_xattr_generic_list.
Also, f2fs_xattr_advise_list is only ever called for
f2fs_xattr_advise_handler; there is no need to double check for that.

We pass 'nfree' to has_not_enough_free_secs to check whether there is
enough free section, but 'nfree' indicates the number of segment gced,
should alter the value to section number.

Third test, using the full device, on linux 4.2.1

Unfortunately, mount failed with. The kernel showed that a high order

Yeah, but I think we need to increase nfre
Thank you for the test.

In update_sit_info, we use div_u64 to handle 'u64 divide u64' case, but
div_u64 can only handle 32-bits divisor, so our divisor with u64 type
passed to div_u64 will overflow, result in the wrong calculation when

I assume I have it, as git pull didn't give me any updates.

I don't know, the documentation isn't very forthcoming with details :)
In any case, this is just for testing. My rationale was that multiple logs
probably means that there ar

Oh, and please, I beg you, consider increasing the hardlink limit to >16
bit - look at other filesystems,. many filesystems thought they could get
away with 16 bit (ext*, xfs, ...) but all of them nowadays support 31
