The brlock was completely removed in the 3.13 kernel series.
see commit 0f6ed63b1707 ("no need to keep brlock macros anymore...")It seems that documentation in seqlock.h was not updated to reflect this. This patch drops the (hopefully last) false brlock reference. All remaining references to brlock refer to byte-range locks (notably in cifs) and not to "Big Reader Lock" and should be correct. patch is against 3.19.0-rc1 linux-next Signed-off-by: Nicholas Mc Guire <[email protected]> --- include/linux/seqlock.h | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/include/linux/seqlock.h b/include/linux/seqlock.h index f5df8f6..af7f5e9 100644 --- a/include/linux/seqlock.h +++ b/include/linux/seqlock.h @@ -13,9 +13,8 @@ * from going forward.
