Mark Salyzyn f20fbdb1b8 [PATCH v4 4/5] pstore: add pmsg ... A secured user-space accessible pstore object. Writes to /dev/pmsg0 are appended to the buffer, on reboot the persistent contents are available in /sys/fs/pstore/pmsg-ramoops-[ID]. One possible use is syslogd, or other daemon, can write messages, then on reboot provides a means to triage user-space activities leading up to a panic as a companion to the pstore dmesg or console logs. Signed-off-by: Mark Salyzyn <salyzyn@android.com> v2: switch from snprintf to scnprintf v3: split out prz_ok checking into PATCH 3/5 replace pmsg_lseek with noop_llseek use pr_fmt() macro make write atomic and use a vmalloc'd bounce buffer v4: use mutex_lock instead of spin_lock. Change-Id: I82a2a9a989d7583c5fcb65ff520027dc3a034a4c Git-commit: 53d8e1c7141617e8656420afb44f9536e7cf0519 Git-repo: https://android.googlesource.com/kernel/common.git Signed-off-by: Ian Maund <imaund@codeaurora.org>		2015-03-19 15:00:02 -07:00
