Under heavy fsstress, we may triggle panic while issuing discard,
because __check_sit_bitmap() detects that discard command may earse
valid data blocks, the root cause is as below race stack described,
since we removed lock when flushing quota data, quota data writeback
may race with

This should just be:
ns->blksize_shift = ns->bdev->bd_inode->i_blkbits;

There is a function named ilog2() exist which can replace blksize.
The generated code will be shorter and more efficient on some
architecture, such as arm64. And ilog2() can be optimized according
to different architecture.

fsck.f2fs reports corruption if the filesystem contains any encrypted +
casefolded directories with any substantial number of dentries:
