  ecryptfs: keep the lower iattr contained in truncate_upper (2026-04-08 18:54:03 -0500)

eCryptfs changes for 7.1-rc1

The set of eCryptfs changes for the 7.1-rc1 merge window consists of:
- A fix to avoid unnecessary eCryptfs inode timestamp truncation by
  re-using the lower filesystem's time granularity
- Various small code cleanups
- Reorganization of the setattr hook's handling of inode resizing to
  improve style and readability, remove an unnecessary memory allocation
  when shrinking, and to support an upcoming rework of the VFS
  interfaces involved in truncation

The patches have all spent time in linux-next and they do not regress
the tests in the ecryptfs-utils tree. The inode timestamp fix returns
the "setattr-flush-dirty" test to passing state.
