this looks like it doesn't apply anymore due to changes in "smb:
client: compress: LZ77 code improvements cleanup"
Let me know if you see any problems building the current for-next
13b68d44990d (HEAD -> for-next, origin/for-next) smb: client:
compress: LZ77 code improvements cleanup
1dcb0b607b9b smb: client: insert compression check/call on write requests
ee71379301eb smb3: mark compression as CONFIG_EXPERIMENTAL and fix
missing compression operation
Enzo,
Is it easier for you to update patch 1 and 3, to make it smaller so
you don't have to add code in patch 1 that you remove in patch 3?
Also let me know if other patches to try?
