Subject: NFS: Fix a refcounting issue in O_DIRECT
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=5a695da26367f53a368c90435e0b883c12f02791;p=~shefty%2Frdma-dev.git

NFS: Fix a refcounting issue in O_DIRECT

In nfs_direct_write_reschedule(), the requests from nfs_scan_commit_list
have a refcount of 2, whereas the operations in
nfs_direct_write_completion_ops expect them to have a refcount of 1.

This patch adds a call to release the extra references.
