similar to: [PATCH v20 19/32] ocfs2: Provide a splice-read stub

Provide a splice_read stub for ocfs2. This emits trace lines and does an atime lock/update before calling filemap_splice_read(). Splicing from direct I/O is handled by the caller. A couple of new tracepoints are added for this purpose. Signed-off-by: David Howells <dhowells at redhat.com> cc: Christoph Hellwig <hch at lst.de> cc: Al Viro <viro at zeniv.linux.org.uk> cc: Jens

From: Zach Brown <zab@zabbo.net> ocfs2''s .aio_read and .aio_write methods are changed to take iov_iter and pass it to generic functions. Wrappers are made to pack the iovecs into iters and call these new functions.

We should call ocfs2_inode_lock_atime instead of ocfs2_inode_lock in ocfs2_file_splice_read like we do in ocfs2_file_aio_read so that we can update atime in splice read if necessary.

Hi Andrew Morton, The patch "[patch 05/22] ocfs2: lighten up allocate transaction" in mm tree is not the newest one, please drop it from mm tree. This patch V3 is newest, please replace it. Thanks. The issue scenario is as following: When fallocating a very large disk space for a small file, __ocfs2_extend_allocation attempts to get a very large transaction. For some journal

Now in ocfs2_local_free_info(), it returns 0 even if it actually fails. Though it doesn't cause any real problem since the only caller dquot_disable() ignores the return value, we'd better return correct as it is.

Hi all and thank you in advance. I have problem connected with to functions basic blocks list splice, I have tried to splice list of basic blocks one function with another and after delete it, I have replaced all uses of this function with another, I have even tried splice basic blocks of copy of this function, but it also does not help, I have got working byte code and I have compiled it by help

Hi, Could you please have a look at https://lkml.org/lkml/2016/2/2/538 and see if this makes any sense to you? I've been checking kernel changes between linux_3.16.7 and linux_3.16.36, and this has popped out. Could this be the reason for the "too many references" errors? Regards, Luis Ugalde.

Hi, A while ago I sent an email regarding these "*ETOOMANYREFS* Too many references: cannot splice." that we've seen since Debian updated the Jessie kernel to 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 while older kernels, like 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64 showed no errors at all. I was wondering if no one

Hi, I often need to take columns from two data.frames and 'splice' them together (alternately taking a column from the first data frame, then from the second). For example: x <- table(sample(letters[1:9], 100, replace=TRUE), sample(letters[1:4], 100, replace=TRUE)) y <- prop.table(x) splice <- function (x, y) { z <- matrix(rep(NA, (ncol(x) * 2) * nrow(x)), nrow
