What it is

In the Linux kernel, the following vulnerability has been resolved:

Revert "fs/ntfs3: Replace inode_trylock with inode_lock"

This reverts commit 69505fe98f198ee813898cbcaf6770949636430b.

Initially, conditional lock acquisition was removed to fix an xfstest bug

that was observed during internal testing. The deadlock reported by syzbot

is resolved by reintroducing conditional acquisition. The xfstest bug no

longer occurs on kernel version 6.16-rc1 during internal testing. I

assume that changes in other modules may have contributed to this.
