btrfs: its btrfs_err() instead of btrfs_error()

2015-07-23T01:20:53+00:00

sorry I indented to use btrfs_err() and I have no idea
how btrfs_error() got there.
infact I was thinking about these kind of oversights
since these two func are too closely named.

btrfs_kobj_add_device() does not need fs_info any more.

btrfs: cleanup 64bit/32bit divs, compile time constants

2015-03-03T16:23:57+00:00

Switch to div_u64 if the divisor is a numeric constant or sum of
sizeof()s. We can remove a few instances of do_div that has the hidden
semtantics of changing the 1st argument.

Small power-of-two divisors are converted to bitshifts, large values are
kept intact for clarity.

Btrfs, raid56: fix use-after-free problem in the final device replace procedure on raid56

2014-12-03T02:18:47+00:00

The commit c404e0dc (Btrfs: fix use-after-free in the finishing
procedure of the device replace) fixed a use-after-free problem
which happened when removing the source device at the end of device
replace, but at that time, btrfs didn't support device replace
on raid56, so we didn't fix the problem on the raid56 profile.
Currently, we implemented device replace for raid56, so we need
kick that problem out before we enable that function for raid56.

The fix method is very simple, we just increase the bio per-cpu
counter before we submit a raid56 io, and decrease the counter
when the raid56 io ends.
