Dezhi Huang c1b1201d39 BACKPORT: FROMLIST: dma-buf: Move sysfs work out of DMA-BUF export path 
We have identified an animation lag issue on our Android 14-6.1 product
which seems to be caused by contention in the rwsem lock during the
dmabuf request process. It appears that other processes are holding
sysfs read locks, resulting in the blocking of dmabuf sysfs node
creation. We encountered an issue in android14-6.1 that is similar to
the problem described in [1]. So we cherry-pick this commit to
android14-6.1.

1. The android14-6.1 KMI is frozen, and the modification to struct
   dma_buf_sysfs_entry in the original patch triggers ABI check
   failures. Instead of an anonymous union, use the existing struct
   kobject directly as a work_struct with type punning.
