Hi Neil,
The first two patches add some necessary sysfs_notify calls for external
metadata arrays. They replace
md-ping-userspace-on-ext-metadata-events.patch which, as you noted, did
these notifications globally in md_check_recovery() rather than at the
local site where the state changes.
While testing these I ran into:
WARNING: at include/linux/blkdev.h:443 queue_flag_clear+0x2c/0x4d()
...due to the recent "block: make queue flags non-atomic" (commit:
75ad23bc0fcb4f992a5d06982bf0857ab1738e9e). I believe patch 3/3 is the
intended fix.
