Signed-off-by: Pavel Butsykin <pbutsykin@virtuozzo.com> ===================== Patchset description: Statistics for vstorage kernel fast-path Vstorage provides plenty of statistics information via 'vstorage -c cl mnt-top', but when it comes kernel fast-path, it doesn't work. All because mnt-top command collects information from .vstorage.info directory, where vstorage-mount provides a lot of different statistical information in the form of files, but it was not implemented for for fast-path. This patch-set is aimed to implementation of the support of some statistics inforamtion files from .vstorage.info: cs_stats fstat fstat_lat iostat requests Which will be located at "/sys/fs/fuse/connections/*mnt_id*/kio_stat/". This will be enough to maintain vstorage mnt-top command for fast-path mount points. https://pmc.acronis.com/browse/VSTOR-20979 Acked-by: Alexey Kuznetsov <kuznet@virtuozzo.com> Pavel Butsykin (14): fs/fuse: add conn_ctl to fuse_conn struct fs/fuse kio: create sysfs stat directory fs/fuse kio: implement iostat statistics info fs/fuse kio: make interface pcs_kio_file_list() for listing kio files fs/fuse kio: make interface pcs_kio_req_list() for listing kio reqs fs/fuse kio: add retry counter for kio requests fs/fuse kio: implement pcs_strerror() fs/fuse kio: implement requests statistics info fs/fuse kio: implement fstat statistics info fs/fuse kio: implement fstat_lat statistics info fs/fuse kio: remove useless pcs_cs initialization fs/fuse kio: implement cs statistics accounting fs/fuse kio: convert rpc state id to string fs/fuse kio: implement cs_stats statistics info --- fs/fuse/kio/pcs/pcs_cs.c | 22 +--------------------- 1 file changed, 1 insertion(+), 21 deletions(-)
