Subject: fuse: fix time_to_jiffies nsec sanity check
From: David Sheets <[email protected]>
commit 210675270caa33253e4c33f3c5e657e7d6060812 upstream.
Commit bcb6f6d2b9c2 ("fuse: use timespec64") introduced clamped nsec values in time_to_jiffies but used the max of nsec and NSEC_PER_SEC - 1 instead of the min. Because of this, dentries would stay in the cache longer than requested and go stale in scenarios that relied on their timely eviction.
