2011-11-22jbd: clear revoked flag on buffers before a new transaction startedYongqiang Yang3-0/+41
Currently, we clear revoked flag only when a block is reused. However, this can tigger a false journal error. Consider a situation when a block is used as a meta block and is deleted(revoked) in ordered mode, then the block is allocated as a data block to a file. At this moment, user changes the file's journal mode from ordered to journaled and truncates the file. The block will be considered re-revoked by journal because it has revoked flag still pending from the last transaction and an assertion triggers. We fix the problem by keeping the revoked status more uptodate - we clear revoked flag when switching revoke tables to reflect there is no revoked buffers in current transaction any more.

2011-11-08n_gsm: Fix timingsAlan Cox1-5/+7
Alek Du reported that the code erroneously applies time to jiffies conversions twice to the t1 and t2 values. In normal use on a modem link this cases no visible problem but on a slower link it will break as with HZ=1000 as is typical we are running t1/t2 ten times too fast. Alek's original patch removed the conversion from the timer setting but we in fact have to be more careful as the contents of t1/t2 are visible via the device API and we thus need to correct the constants.

2011-11-07VFS: we need to set LOOKUP_JUMPED on mountpoint crossingAl Viro1-1/+15
Mountpoint crossing is similar to following procfs symlinks - we do not get ->d_revalidate() called for dentry we have arrived at, with unpleasant consequences for NFS4. Simple way to reproduce the problem in mainline: cat >/tmp/a.c <<'EOF' #include <unistd.h> #include <fcntl.h> #include <stdio.h> main() { struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1}; if (fcntl(0, F_SETLK, &fl)) perror("setlk"); } EOF cc /tmp/a.c -o /tmp/test then on nfs4: mount --bind file1 file2 /tmp/test < file1 # ok /tmp/test < file2 # spews "setlk: No locks available"... What happens is the missing call of ->d_revalidate() after mountpoint crossing and that's where NFS4 would issue OPEN request to server. The fix is simple - treat mountpoint crossing the same way we deal with following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

2011-11-07forcedeth: Improve stats countersMandeep Baines1-0/+4
Rx byte count was off; instead use the hardware's count. Tx packet count was counting pre-TSO packets; instead count on-the-wire packets. Report hardware dropped frame count as rx_fifo_errors. - The count of transmitted packets reported by the forcedeth driver reports pre-TSO (TCP Segmentation Offload) packet counts and not the count of the number of packets sent on the wire. This change fixes the forcedeth driver to report the correct count. Fixed the code by copying the count stored in the NIC H/W to the value reported by the driver. - Count rx_drop_frame errors as rx_fifo_errors: We see a lot of rx_drop_frame errors if we disable the rx bottom-halves for too long. Normally, rx_fifo_errors would be counted in this case. The rx_drop_frame error count is private to forcedeth and is not reported by ifconfig or sysfs. The rx_fifo_errors count is currently unused in the forcedeth driver. It is reported by ifconfig as overruns. This change reports rx_drop_frame errors as rx_fifo_errors.

2011-11-07drivers/md: change module.h -> export.h in persistent-data/dm-*Paul Gortmaker4-4/+4
For the files which are not themselves modular, we can change them to include only the smaller export.h since all they are doing is looking for EXPORT_SYMBOL. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-11-07arm: Add export.h to recently added files for EXPORT_SYMBOLPaul Gortmaker2-0/+2
These files didn't exist at the time of the module.h split, and so were not fixed by the commits on that baseline. Since they use the EXPORT_SYMBOL and/or THIS_MODULE macros, they will need the new export.h file included that provides them.

2011-11-07Revert "hvc_console: display printk messages on console."Linus Torvalds1-6/+1
This reverts commit 361162459f62dc0826b82c9690a741a940f457f0. It causes an infinite loop when booting Linux under Xen, as so: [ 2.382984] console [hvc0] enabled [ 2.382984] console [hvc0] enabled [ 2.382984] console [hvc0] enabled ... as reported by Konrad Rzeszutek Wilk. And Rusty reports the same for lguest. He goes on to say: "This is not a concurrency problem: the issue seems to be that calling register_console() twice on the same struct console is a bad idea." and Greg says he'll fix it up properly at some point later. Revert for now.
