libceph: stop parsing when a bad int arg is detected

There is no reason to continue option parsing after detecting bad option. [ Return match_int() errors from ceph_parse_options() to match the behaviour of parse_rbd_opts_token() and parse_fsopt_token(). ] Signed-off-by: Chengguang Xu Reviewed-by: Ilya Dryomov Signed-off-by: Ilya Dryomov

Merge tag 'ceph-for-4.17-rc1' of git://github.com/ceph/ceph-client

Pull ceph updates from Ilya Dryomov: "The big ticket items are: - support for rbd "fancy" striping (myself). The striping feature bit is now fully implemented, allowing mapping v2 images with non-default striping patterns. This completes support for --image-format 2. - CephFS quota support (Luis Henriques and Zheng Yan). This set is based on the new SnapRealm code in the upcoming v13.y.z ("Mimic") release. Quota handling will be rejected on older filesystems. - memory usage improvements in CephFS (Chengguang Xu). Directory specific bits have been split out of ceph_file_info and some effort went into improving cap reservation code to avoid OOM crashes. Also included a bunch of assorted fixes all over the place from Chengguang and others" * tag 'ceph-for-4.17-rc1' of git://github.com/ceph/ceph-client: (67 commits) ceph: quota: report root dir quota usage in statfs ceph: quota: add counter for snaprealms with quota ceph: quota: cache inode pointer in ceph_snap_realm ceph: fix root quota realm check ceph: don't check quota for snap inode ceph: quota: update MDS when max_bytes is approaching ceph: quota: support for ceph.quota.max_bytes ceph: quota: don't allow cross-quota renames ceph: quota: support for ceph.quota.max_files ceph: quota: add initial infrastructure to support cephfs quotas rbd: remove VLA usage rbd: fix spelling mistake: "reregisteration" -> "reregistration" ceph: rename function drop_leases() to a more descriptive name ceph: fix invalid point dereference for error case in mdsc destroy ceph: return proper bool type to caller instead of pointer ceph: optimize memory usage ceph: optimize mds session register libceph, ceph: add __init attribution to init funcitons ceph: filter out used flags when printing unused open flags ceph: don't wait on writeback when there is no more dirty pages ...

ceph: quota: add initial infrastructure to support cephfs quotas

2018-04-02T09:17:51+00:00

This patch adds the infrastructure required to support cephfs quotas as it is currently implemented in the ceph fuse client. Cephfs quotas can be set on any directory, and can restrict the number of bytes or the number of files stored beneath that point in the directory hierarchy. Quotas are set using the extended attributes 'ceph.quota.max_files' and 'ceph.quota.max_bytes', and can be removed by setting these attributes to '0'.
