Memory amount is increased before a successful write-read
sequence is done. Thus, 512 kB of onboard memory is detected
on memoryless cards like SB32.

The direction of rounding is incorrect in the snd_interval_ratnum()
It was detected with following parameters (sb8 driver playing
8kHz stereo file):
 - num is always 1000000
 - requested frequency rate is from 7999 to 7999 (single frequency)

The first loop calculates div_down(num, freq->min) which is 125.
Thus, a frequency range's minimum value is 1000000 / 125 = 8000 Hz.
The second loop calculates div_up(num, freq->max) which is 126
The frequency range's maximum value is 1000000 / 126 = 7936 Hz.
The range maximum is lower than the range minimum so the function
fails due to empty result range.

Fixed a typo of the max buffer size specified for buffer allocation
changed in the commit d6797322.
Signed-off-by: Takashi Iwai <tiwai@suse.de>

When allocating the PCM buffer, use vmalloc_user() instead of vmalloc().
Otherwise, it would be possible for applications to play the previous
contents of the kernel memory to the speakers, or to read it directly if
the buffer is exported to userspace.

  xfs: improve metadata I/O merging in the elevator
  xfs: check for not fully initialized inodes in xfs_ireclaim

Commit 3d1e4631 ("get rid of init_file()") removed the export of
alloc_file() -- possibly inadvertently, since that commit mainly
consisted of deleting the lines between the end of alloc_file() and
the start of the code in init_file().

There is in fact one modular use of alloc_file() in the tree, in
drivers/infiniband/core/uverbs_main.c, so re-add the export to fix:

    ERROR: "alloc_file" [drivers/infiniband/core/ib_uverbs.ko] undefined!

when CONFIG_INFINIBAND_USER_ACCESS=m.

As predicted during code review, the sysctl(2) changes made systems with

The code in xfs_free_buf() only attempts to free the b_pages array if the
buffer is a page cache backed or page allocated buffer. The extra log buffer
that is used when the log wraps uses pages that are allocated to a different
log buffer, but it still has a b_pages array allocated when those pages
are associated to with the extra buffer in xfs_buf_associate_memory.

Hence we need to always attempt to free the b_pages array when tearing
down a buffer, not just on buffers that are explicitly marked as page bearing
buffers. This fixes a leak detected by the kernel memory leak code.

Change all async metadata buffers to use [READ|WRITE]_META I/O types
so that the I/O doesn't get issued immediately. This allows merging of
adjacent metadata requests but still prioritises them over bulk data.
This shows a 10-15% improvement in sequential create speed of small
files.

Don't include the log buffers in this classification - leave them as
sync types so they are issued immediately.
