Commit 3e6053d76dcbd92b2f9f4ad5ece9bce83149523e adds a gfp_mask parameter
to blkdev_issue_discard, which breaks compilation in btrfs if BIO_RW_DISCARD
is config'ed in:
/home/diego/kernel/btrfs-unstable-standalone/extent-tree.c:1896: error:
too few arguments to function 'blkdev_issue_discard'
I added the parameter - GFP_KERNEL, which is what was the gfp_mask used
before this change.
