Sleeper Fairness is a concept used by CFS which treat sleeping/waiting tasks as if they were in a run queue. This implies tasks which spend most of the time waiting for an user input and such will get a fair share of CPU when they need it. Disabling Gentle Fair Sleepers could improve UI responsiveness.

Zram currently uses LZO compression. With Snappy, it uses less CPU time and is
thus more useful. The sacrifice in compression ratio is small.
Zram's LZO and Snappy support can be independently enabled at compile time and
each zram device can switch between compression methods when unused.
When only a single compression method was enabled at compile time, no idirection
penalty is incurred.

The current code for PIO doesn't transfer whole data when data size
is not in multiple of 4 bytes. The last few bytes are not written to
the card resulting in no DATAEND interrupt from SDCC. This patch
allows data transfer for non-aligned data size in PIO mode.
Enable prog done interrupt for stop command(CMD12) that is sent
after a multi-block write(CMD25). The PROG_DONE bit is set when
the card has finished its programming and is ready for next data.
After every write request the card will be polled for ready status
using CMD13. For a multi-block write(CMD25) before sending CMD13,
stop command (CMD12) will be sent. If we enable prog done interrupt
for CMD12, then CMD13 polling can be avoided. The prog done interrupt
means that the card is done with its programming and is ready for
next request.
In the context of request processing thread, data mover lock is
acquired after the host lock. In another context, in the completion
handler of data mover the locks are acquired in the reverse order,
resulting in possible circular lock dependency warning. Hence,
schedule a tasklet to process the dma completion so as to avoid
nested locks.
CONFIG_MMC_MSM7X00A_RESUME_IN_WQ and CONFIG_MMC_EMBEDDED_SDIO don't exist
in Kconfig and is never defined anywhere else, therefore removing all
references for it from the source code.
fudgeswap acts as follows:
If set to non zero (defualt is 512k):
Check for the amount of SWAP_FREE space avalible
If > 0KB is avalible:
if fudgeswap > swapfree:
other_file += swapfree
else:
other_file += fugeswap
In short: we will add in fugeswap as long as its less then the free swap
Setting this to a very large positive number will indicate swap ought
to be fully used as free (and will slow the system down)
smaller numbers will allow you to put some pressure on SWAP without
slowing the system down as much.
small negitive numbers will allow the system to be faster at the same
minfree level.
default is 512 to give a very little bit of pressure to use some swap
but this can be modified at runtime via:
/sys/module/lowmemorykiller/parameters/fugeswap
