Investigate unnecessary writes

[InnovativeInventor]

When viewing the logs of a git clone operation, there appears to be unnecessary writes occurring:

[2023-01-07T17:48:25Z DEBUG fuser::request] FUSE(5330) ino 0x0000000000000162 WRITE fh FileHandle(55), offse
t 200703, size 1, write flags 0x0
[2023-01-07T17:48:25Z DEBUG fuser::request] FUSE(5332) ino 0x0000000000000162 WRITE fh FileHandle(55), offse
t 200704, size 4095, write flags 0x0
[repeat]

Why are writes of size 1 occurring? Is this standard practice? Or, this could be an upstream issue.

Looks like this originates from aligned_sub_buf here:

This may be reasonable behavior, then (or perhaps an off-by-one issue).
