[PATCH 1/4 v2] Btrfs: check write access to mount earlier while creating snapshots

Move check of write access to mount into upper functions so that we can use mnt_want_write_file instead, which is faster than mnt_want_write. Signed-off-by: Liu Bo liubo2...@cn.fujitsu.com --- fs/btrfs/ioctl.c | 22 +++--- 1 files changed, 11 insertions(+), 11 deletions(-)

[PATCH 2/4 v2] Btrfs: remove redundant r/o check for superblock

mnt_want_write() and mnt_want_write_file() will check sb-s_flags with MS_RDONLY, and we don't need to do it ourselves. Signed-off-by: Liu Bo liubo2...@cn.fujitsu.com --- fs/btrfs/ioctl.c |7 --- 1 files changed, 0 insertions(+), 7 deletions(-) diff --git a/fs/btrfs/ioctl.c

[PATCH 4/4 v2] Btrfs: do not set subvolume flags in readonly mode

$ mkfs.btrfs /dev/sdb7 $ btrfstune -S1 /dev/sdb7 $ mount /dev/sdb7 /mnt/btrfs mount: block device /dev/sdb7 is write-protected, mounting read-only $ btrfs dev add /dev/sdb8 /mnt/btrfs/ Now we get a btrfs in which mnt flags has readonly but sb flags does not. So for those ioctls that only check

[PATCH 1/3] Btrfs-progs: add support to set subvolume/snapshot readonly

Setting subvolume/snapshot readonly has been missing for a long time. With this patch, we can set a subvolume/snapshot readonly via: obtrfs subvolume set-ro path Signed-off-by: Liu Bo liubo2...@cn.fujitsu.com --- cmds-subvolume.c | 40 ioctl.h

[PATCH 2/3] Btrfs-progs: make get default report correctly

We have both set-default and get-default, but actually our get-default does not show which one is the default one. This patch plus the kernel side patch fix this. Signed-off-by: Liu Bo liubo2...@cn.fujitsu.com --- Makefile |6 +++--- btrfs-list.c | 44

[PATCH 3/3] Btrfs-progs: add 's' option for 'btrfs subvolume list'

We want 'btrfs subvolume list' to act as 'ls', which means that we can not only list out all the subvolumes we have, but also list each single one. So this patch add 's' option to show a single one: $ ./btrfs sub list /mnt/btrfs/ ID 256 top level 5 path subvol (Readonly,) ID 257 top level 5 path

[PATCH 1/3] Btrfs: add default support for subvol getflags

This is kernel side patch for 'btrfs subvolume get-default'. Our 'btrfs subvolume get-default' did not work as wish, because we do not have APIs to fetch the subvolume's default state. This patch treats default state as a flag and returns it to user space. Signed-off-by: Liu Bo

[PATCH 2/3] Btrfs: update subvol_getflags/setflags to know new args from user

I've modified 'btrfs subvolume list' to show a subvolume's attributes, such as readonly and default, and adopted a new structure for args for subvol_getflags/setflags. So here is the kernel side update. Signed-off-by: Liu Bo liubo2...@cn.fujitsu.com --- fs/btrfs/ioctl.c | 100
