quota/marker: fix inode quota with rename
There are three problems with marker-rename which is fixed in this patch Problem 1) 1) mq_reduce_parent_size is not handling inode-quota contribution 2) When dest files exists and IO is happening Now renaming will overwrite existing file mq_reduce_parent_size called on dest file with saved contribution, this can be a problem is IO is still happening contribution might have changed Problem 2) There is a small race between rename and in-progress write Consider below scenario 1) rename FOP invoked on file 'x' 2) write is still in progress for file 'x' 3) rename takes a lock on old-parent 4) write-update txn blocked on old-parent to acquire lock 5) in rename_cbk, contri xattrs are removed and contribution is deleted and lock is released 6) now write-update txn gets the lock and updates the wrong parent as it was holding lock on old parent so validate parent once the lock is acquired Problem 3) when a rename operation is performed, a lock is held on old parent. This lock is release before unwinding the rename operation. This can be a problem if there are in-progress writes happening during rename, where update txn can take a lock and update the old parent as inode table is not updated with new parent Change-Id: Ic3316097c001c33533f98592e8fcf234b1ee2aa2 BUG: 1240991 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/11578 Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
