Kernel version to apply it to: 6.18-stable tree
Hi stable@,
Chris Mason recently detected that this patch is a required dependency
for commit 5b804b8f1e0d ("io_uring/rsrc: fix lost entries after cloned
range") in the 6.18-stable tree [1]. Without this patch, the changes
in commit 5b804b8f1e0d use an incorrect value for nbufs when it
assigns "i = nbufs" [2].
Could you please apply this patch to the 6.18-stable tree as a
dependency fix needed for commit 5b804b8f1e0d?
Thanks,
Joanne
