Add device-links after the devices are created (but before they are
probed) by looking at common DT bindings like clocks and
interconnects.
Automatically adding device-links for functional dependencies at the

Modeled after commit b886ee3e778e ("ext4: Support case-insensitive file

This patch implements the actual support for case-insensitive file name
lookups in f2fs, based on the feature bit and the encoding stored in the
superblock.
A filesystem that has the casefold feature set is
Add charset encoding to f2fs to support casefolding. It is modeled after
the same feature introduced in commit c83ad55eaa91 ("ext4: include charset

Currently this is not compatible with encryption, similar to the current
ext4 imlpementation. This will chang
In preparation for including the casefold feature within f2fs, elevate
the EXT4_CASEFOLD_FL flag to FS_CASEFOLD_FL.

Perhaps specify "linux-distros@" without a domain, so it's more clear?

Thanks for all the help and testing you provided. It's good to know
these changes have passed at least some scheduler regression tests.

Changelog v6
- Added back missing call to lsub_positive(&cfs_b->runtime, runtime);
- Added Reviewed-by: Ben Segall
- Fix some grammar in the Documentation, and change some wording.
- Updated documentation due to the .rst change
Changelog v5
- Based on this comment from Ben Segall's comment on v4
It has been observed, that highly-threaded, non-cpu-bound applications
running under cpu.cfs_quota_us constraints can hit a high percentage of
periods throttled while simultaneously not consuming the allocated
amount of quota. This use case is typical of user-interactive non-cpu

So this appears to be identical to the patch you sent three days ago; is
there a reason why you are sending it again now?
