Subject: btrfs: adjust while loop condition in run_delalloc_nocow
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0ed30c17f699d5df73c445999b0114c5859d1145;p=linux.git

btrfs: adjust while loop condition in run_delalloc_nocow

We have the following pattern

while (1) {
	if (cur_offset > end)
		break;
}

Which is just

while (cur_offset <= end) {
	...
}

so adjust the code to be more clear.
