This is a regression testcase to check whether we will handle out-of-space case correctly during fallocate() on pinned file once we disable checkpoint.
Testcase: 1. mount f2fs w/ checkpoint=disable option 2. create fragmented file data 3. set flag w/ pinned flag 4. fallocate space for pinned file, expects panic due to running out of space. We should apply both commit ("f2fs: fix to avoid panic once fallocation fails for pinfile") and commit ("f2fs: fix to avoid running out of free segments") to avoid system panic. Note that w/ these two commit, we fixed such issue in both convential and zoned block device.
