From 190791ed65ad41d9261f50bdf8a33a0bc005e7bc Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 14 May 2021 18:21:37 -0400 Subject: [PATCH] nfsd: move some commit_metadata()s outside the inode lock [ Upstream commit eeeadbb9bd5652c47bb9b31aa9ad8b4f1b4aa8b3 ] The commit may be time-consuming and there's no need to hold the lock for it. More of these are possible, these were just some easy ones. Signed-off-by: J.
