Add a sysfs attr that LLDD can configure it for every host. We made
a example in hisi_sas. Other LLDDs using libsas can implement it if

Each request type sent to the LightNVM subsystem requires different
metadata. Until now, we have tailored this metadata based on write, read

When a line is selected for recycling by the garbage collector (GC), the
line state changes and the invalid bitmap is frozen, preventing
invalidations from happening. Throughout the GC, the L2P map is checked

is done before the

Hi Jens,
Here is the pblk patchset for this window.
The most notable patches are on the read path:
- ("lightnvm: pblk: check lba sanity on read path") uses the lba
stored on the out-of-bound area to verify that the read ppa
corresponds to the lba pointed to by the read bio.
- ("lightn
When a REQ_FLUSH reaches pblk, the bio cannot be directly completed.
Instead, data on the write buffer is flushed and the bio is completed on
the completion pah. This might require some sectors to be padded in
order to guarantee a successful write.
This patch fixes a memory leak on the padded page
On REQ_PREFLUSH, directly tag the I/O context flags to signal a flush in
the write to cache path, instead of finding the correct entry context
and imposing a memory barrier. This simplifies the code and might
potentially prevent race conditions when adding functionality to the
write path.
Signed-o
As part of pblk's recovery scheme, we store the lba mapped to each
physical sector on the device's out-of-bound (OOB) area. On the read
path, we can use this information to validate that the data being
delivered to the upper layers corresponds to the lba being requested.
The cost of this check is a
Fix stat counter to collect the right number of I/Os being synced on the

The data buffer for the GC path allocates virtual memory through
vmalloc. When this change was introduced, a flag signaling kmalloc'ed
memory was wrongly introduced. Use the right flag when creating a bio
from this buffer.
Fixes: de54e703a422 ("lightnvm: pblk: use vmalloc for GC data buffer")

This patch adds Broadcom FlexRM low-level reset for
VFIO platform.
It will do the following:
1. Disable/Deactivate each FlexRM ring
2. Flush each FlexRM ring
The cleanup sequence for FlexRM rings is adapted from
Broadcom FlexRM mailbox driver.

Hi Vikram,
This patch adds one static ida variable to manage SPI bus number, moreover
we can get dynamic bus number from ida instead of one "dynamic" IDs, which
can be removed.

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.
This issue was detected by using the Coccinelle software.
