Subject: [PATCH 1/1] [TASK] Calculated hash of File object is never used

The indexing pre-calculates the file hash and stores it in
the sys_file table. Sadly the getter of file objects never looks
at this again and always recalculates the hash via the driver,
which is very slow.

Resolves: #54235
Releases: 6.2, 6.1, 6.0
