Technical Description
In the Linux kernel, the following vulnerability has been resolved:
f2fs: flush inode if atomic file is aborted
Let's flush the inode being aborted atomic operation to avoid stale dirty

This triggers f2fs_bug_on() in f2fs_evict_inode:
f2fs_bug_on(sbi, is_inode_flag_set(inode, FI_DIRTY_INODE));
This fixes the syzbot report:
loop0: detected capacity change from 0 to 131072
F2FS-fs (loop0): invalid crc value
F2FS-fs (loop0): Found nat_bits in chec
