Sparse reports: fs/xfs/xfs_log_cil.c:1127:1: warning: context imbalance in 'xlog_cil_push_work' - different lock contexts for basic block fs/xfs/xfs_log_cil.c:1380:1: warning: context imbalance in 'xlog_cil_push_background' - wrong count at exit fs/xfs/xfs_log_cil.c:1623:9: warning: context imbalance in 'xlog_cil_commit' - unexpected unlock xlog_cil_push_background() has a locking annotations for an rw_sem. Sparse does not track lock contexts for rw_sems, so the annotation generates false warnings. Remove the annotation. xlog_wait_on_iclog() drops the log->l_ic_loglock. The function has a sparse annotation, but the prototype in xfs_log_priv.h does not. Hence the warning from xlog_cil_push_work() which calls xlog_wait_on_iclog(). Add the missing annotation.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
