[PATCH] [GFS2] set plock owner in GETLK info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: David Teigland <[email protected]>

Set the owner field in the plock info sent to userspace for GETLK.
Without this, gfs_controld won't correctly see when the GETLK from a
process matches one of the process's existing locks.
