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.
Ext4 and F2fs will switch to these common implementations.

Can you make the structure generic since it is th

It would be helpful to add a few more details in this commit message.
Somewhat along the lines of:

This adds a case insensitive hash function to allow taking the hash
without needing to allocate a casefolded copy of the string.

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.

If two readahead threads having same offset enter in readpages, every read
IOs are split and issued to the disk which giving lower bandwidth.
This patch tries to avoid redundant readahead calls.

When f2fs_ioc_gc_range performs multiple segments gc ops, the return
value of f2fs_ioc_gc_range is determined by the last segment gc ops.
If its ops failed, the f2fs_ioc_gc_range will be considered to be failed
despite some of previous segments gc ops succeeded. Therefore, so we
