One segment will contain many blocks, node and data will not be the
same segment.
Take data block for example, Will Hot data and Warm data and Cold data
in same segment?

This adds a case insensitive hash function to allow taking the hash
without needing to allocate a casefolded copy of the string.
The existing d_hash implementations for casefolding allocate memory
within rcu-walk, by avoiding it we can be more efficient and avoid
worrying about a failed allocation
This lays the ground work for enabling casefolding and encryption at the
same time for ext4 and f2fs. A future set of patches will enable that
functionality.
These unify the highly similar dentry_operations that ext4 and f2fs both
use for casefolding. In addition, they improve d_hash by not requir
This adds general supporting functions for filesystems that use
utf8 casefolding. It provides standard dentry_operations and adds the
necessary structures in struct super_block to allow this standardization.
The new dentry operations are functionally equivalent to the existing
operations in ext4 a
This switches ext4 over to the generic support provided in
the previous patch.
Since casefolded dentries behave the same in ext4 and f2fs, we decrease
the maintenance burden by unifying them, and any optimizations will
immediately apply to both.

I thought it's working for our system. But as you said, it might be
not true for others. I got your point. Partition label would be a
great idea for us.
Thank you for your comment!

When end_addr comes to zero, it'll trigger different behaviour.
To prevent this, we need to ignore the case of that range.len is
zero in the function.

I thought it's better to treat this as the error case, since the range
already passed out of the i_size range.
If we allow that, the user needs to send the range parameter being
aligned like start:0 and len: roundup(i_size, PAGE_SIZE), even if he
or she wants to erase the whole file.
