I noticed 6.1.140 build failure(fs/btrfs/discard.c:247:5: error: implicit declaration of function 'ASSERT')
fs/btrfs/discard.c: In function 'peek_discard_list': fs/btrfs/discard.c:247:5: error: implicit declaration of function 'ASSERT'; did you mean 'IS_ERR'? [-Werror=implicit-function-declaration] ASSERT(block_group->discard_index != ^~~~~~ IS_ERR
It seems realted to the patch(btrfs-fix-discard-worker-infinite-loop-after-disabling-discard.patch).
Yes, it is.
The patch, like most stable backports, was automatically picked by the stable scripts and added to stable releases. I assume that before the release was made, it was compile tested by the stable automatic processes.
I just tried it, and it compiles successfully for me:

I walked around it with the following patch.
In the future please cc the stable list when you find problems with stable backports.
