This small patchset introduces a non-blocking version of cma_release()

cma_release() has to lock the cma_lock mutex to clear the cma bitmap.
It makes it a blocking function, which complicates its usage from

It doesn't.
Hello Linus,

Pass a bio to decrypt_bio instead of a buffer_head to decrypt_bh.
Another step towards doing decryption per-BIO instead of per-BH.

Use the new decrypt_end_bio() instead of readpage_end_bio() if
fscrypt needs to be used. Remove the old end_buffer_async_read()
now that all BHs go through readpage_end_bio().

This new data structure allows a task to wait for N things to complete.
Usually the submitting task will handle cleanup, but if it is killed,
the last completer will take care of it.

If the filesystem returns an error from get_block, report it
instead of ineffectually setting PageError. Don't bother starting
any I/Os in this case since they won't bring the page Uptodate.

This patchset does I/Os in larger chunks, if the blocks are adjacent.
More importantly, it returns the actual error from ->readpage for
filesystems which use block_read_full_page(). Unless fscrypt returns
an error, in which case it turns into EIO because it has to roundtrip
through bi_status.

Use the new blk_completion infrastructure to wait for multiple I/Os.
Also coalesce adjacent buffer heads into a single BIO instead of
submitting one BIO per buffer head. This doesn't work for fscrypt yet,
so keep the old code around for now.

This is prep work for doing decryption at the BIO level instead of
the BH level. It still works on one BH at a time for now.

Oops, this is broken, I'll send a v2 soon.

Hi Tony,
I love your patch! Perhaps something to improve:

According to board schematic, PHY provides both, RX and TX delays.
However, according to "fix" Realtek provided for this board, only TX
delay should be provided by PHY.
Tests show that both variants work but TX only PHY delay works
slightly better.
