v14:
Splits refactoring part of btrfs_free_stale_devices() into a new patch
v13:
Please ref individual patches.
v12:
Fixed coding style - leave space between " : ".
v11:
btrfs-progs: Bring the code into the else part of if(forget).
Use strerror to print the erorr instead of ret.
v10:
Make btrfs-progs changes more readable.
With an effort to keep the known bug [1] as it is..
[1]
The cli 'btrfs device scan --all /dev/sdb' which should have scanned
only one device, ends up scanning all the devices and I am not trying
to fix this bug in this patch because..
. -d|--all is marked as deprecated, I hope -d option would go away
. For now some script might be using this bug as a feature, and fixing
this bug might lead to mount failure.
v9:
Make forget as a btrfs device scan option.
Use forget in the fstests, now you can run fstests with btrfs as rootfs
which helps to exercise the uuid_mutex lock.
v8:
Change log update in the kernel patch.
v7:
Use struct btrfs_ioctl_vol_args (instead of struct
btrfs_ioctl_vol_args_v2) as its inline with other ioctl
btrfs-control
The CLI usage/features remains same. However internally the ioctl flag
is not required to delete all the unmounted devices. Instead leave
btrfs_ioctl_vol_args::name NULL.
v6:
Use the changed fn name btrfs_free_stale_devices().
Change in title:
Old v5:
Cover-letter:
[PATCH v5] Add cli and ioctl to ignore a scanned device
Kernel:
[PATCH v5] btrfs: introduce feature to ignore a btrfs device
Progs:
[PATCH v5] btrfs-progs: add 'btrfs device ignore' cli
v5:
Adds feature to delete all stale devices
Reuses btrfs_free_stale_devices() fn and so depends on the
patch-set [1] in the ML.
Uses struct btrfs_ioctl_vol_args_v2 instead of
struct btrfs_ioctl_vol_args as arg
Does the device path matching instead of btrfs_device matching
(we won't delete the mounted device as btrfs_free_stale_devices()
checks for it)
v4:
No change. But as the ML thread may be confusing, so resend.
v3:
No change. Send to correct ML.
v2:
Accepts review from Nikolay, details are in the specific patch.
Patch 1/2 is renamed from
